I saw a supernova

It has been a terribly long time since I last managed to get out with the scope, but last night we finally did it! Off to Heathcote because it's the start of dark night.We took both the 5" Tak and the 16" Dob, and got set up nice and early so that we had time for the obligatory admiring of everyone else's scopes before HOORAY the stars came out and I could finally align.

I planned to look at a bunch of double stars, and I did, but then I realised that some of the ones I'd thought to see had a too-small separation so that made me sad. Still, the ones I bagged were very pretty, so that was nice.

After that... well, there was a bit of random looking. But yes, my title is indeed accurate: someone announced to the world at large that they knew a supernova had appeared in NGC1365 (better known to you and me as the Zorro galaxy, because it looks like a Z), so there was a bit of a rush to find it. And there it was: a star that was not there last time we looked at that galaxy. It's only about 5 days (... and however many million light years...) old. I cannot begin to explain how incredibly excited I was.

What else? I am utterly standing by the idea that I found Uranus - I swear it looked vaguely blue and disk-like - and I know that I found Neptune, so that was very nice. I get a good view of the Small Magellanic in my Tak; that is, I can see the whole lot, which is pretty cool.

Thanks to J's Dob, we saw a number of faint fuzzies, some of which even looked like galaxies: the Grus quartet in particular, a few in Fornax and Sculptor... the one knows as the Cigar is pretty cool because it's (relatively) so big. However nothing is quite as cool as Andromeda, which we got to see through our neighbour's 20" Dob because he was (deliberately) in a very good position for the northern sky - and it was amazing. (Although not as cool as a supernova.)

Finally, after much frustration with trees, Orion made it up to clear viewing so I got to finish off the night in the best way possible. I will never, ever get bored by the Orion Nebula. I promise. I love my Tak because I can effectively zoom in to see the Trapezium and try to ferret out the last two faint stars... or I can have the whole view of the entire nebula (well, nearly) and just amuse myself by finding shapes in the dust.

Also, Jupiter too made it over the trees... well and J manhandled the scope so that it was in a better viewing position. So I got to totally blow my night vision on it, which was cool, although the seeing was a bit mush. The four Galilean moons were out in glory, and I definitely saw three cloud bands with maybe some mottling around one pole.

We made it to about 1am. I had thought, early in the night, that going the freezer suit was the weak option... especially when the Norwegian neighbour mentioned he used to wear one observing IN NORWAY and when the Scottish neighbour mentioned observing in MINUS 26 DEGREES. But whatever. I was glad by the time we were packing up.

Naked-eye planets

There's been a bit of stuff even in mainstream media about four planets being visible in the morning sky at the moment. I didn't think I had a chance of seeing them, because Melbourne has well and truly turned on winter. However, we were up at 6am this morning for a different reason, and there was one big break in the clouds:

Venus, very bright white;

Mercury, faint but not as faint as I expected up to the right of Venus;

Jupiter, looking faintly yellow and about as bright as Venus;

and Mars, definitely red, just above the tops of the houses.

This has made my week! I can't believe I've now seen Mercury with my own eyes; and it was a seriously beautiful sight as a whole.

Last night of astroholiday

The wind did not let up for our last night of our astroholiday, but we went out anyway. J had earlier set up the PST for a bit of solar viewing - and in order to do that, put the double plate on the Losmandy mount. Since it was on there anyway, we decided to try the double up: the 128 and the 90mm. Put the 10mm eyepiece in the 128 and 21mm in the other, with the idea that this would give quite a different view of various objects. It was good in theory, I think, and certainly did give different views. However, it was quite heavy, and seemed to have a bit of trouble moving via the hand controls; this was probably partly to do with the wind, but may als mean we didn't have it quite balanced right.

Anyway, I naturally started out with Jupiter, and it was actually good enough seeing that I put the 6mm in Keppler, and magnified it with the 5mm even. A couple of dark bands were obvious.

I decided to continue my little Messier marathon from last night, since I knew I'd missed a few by looking when they had gone behind the house. I caught M78 - which is a neat splodge of nebulosity with two stars seemingly embedded in it; and M37, which in the 10mm was large, faint, with many distinct stars; in the 21mm, more of a grey smudge, although some individual points were still distinct. M36 looked similar, with a shape I'm claiming as like a starfish. I missed M74, M38, and M34 by not being quick enough! So I went to some others: M48 is still a boring open cluster, but M79 is endearing itself by being such a cute little globular.

I was getting a bit put out by the wind by this stage, so J dragged me over to Copernicus and showed me the Grus quartet (which was actually a triplet at this stage, because it wasn't quite dark enough for the whole show), which is always cool: seeing three or four galaxies apparently so close together is breathtaking. He also showed me NGC246, which he is quite in love with: it's a planetary nebula, with three bright points within/to the side; I'm not sure whether they're physically associated with it or not.

We decided to call it an earlier night than normal, so to finish up I dialled up the Popular Deep Sky Objects tour and had a quick spin. I tried for the Witchhead Nebula, knowing it was going to be too big to see the whole thing in one eyepiece (3 degrees!), but hoping I would at least be able to see some nebulosity. I am dubious, although J claims it was obviously greyer in some sections. 47Tuc - such a bright core, so striking an object! - and, of course, the Orion Nebula finished the night off.

And then there was wind

Even more wind last night. Still, at least it kept the possibility of mozzies at bay.

Tragically, I discovered that I could my thumbs all the way through the thumbs of my gloves... very sad. Especially since it got awfully cold.

Anyway, I decided to do a mini Messier marathon for this session, since that required no planning on my part and hey, it's the Messier catalogue! I did try looking at Jupiter first of course, but again it was mush; the seeing was atrocious in the west, and again the wind was not playing nice.

M79: lovely little globular cluster. A couple of bright stars to the side, better with averted vision. Quite irregular.
M77: itty little galaxy. Better in Copernicus with the 10mm, but still no details obvious.
M42 and 43: a favourite, of course. I looked at the Trapezium, and am convinced that I could see three additional faint stars in between the main bright ones. I tried putting the 6mm in, but the wind made focussing a nightmare.
M41: in Copernicus with the 21mm, very bright and interesting; numerous yellow and bright white stars. With the 35mm, boring. In Keppler, the 10mm gave a chaotic and somewhat overwhelming view of the cluster; the 21mm made it more coherent, and showed off the lovely yellow stars in the centre.
M50: chaotic in the 10mm, boring through the 21mm.
M47: a nice enough little cluster with a somewhat interesting arrangement; I liked the line of bright stars through the middle.
M46: could not be seen in the same field of view as M47 through Keppler; good case in point of how awesome Ptolemy is, for wide views. A bit boring, overall, although exciting to see the planetary nebula off to the side (NGC2438).
M45: in Copernicus, it was a group of bright dots with what is apparently nebulosity, but it just looked like haze around individual stars to me. The Pleiades is, I think, best naked eye.
M93: boring... looks a bit like an anvil. Or maybe a teapot.
M48: chaotic in the 10mm; 21mm made it look like the outline of something I couldn't quite figure out.
M67: looks a bit like a comma. Possibly some nebulosity?
M44: some trouble finding this as the Argo thought it was upside down... impossible int he 10mm, and no shape in the 21mm - just looked like a bunch of visual double and triples. Again, more interesting naked eye, where it was a pronounced smudge.
M1: large grey smudge in Copernicus; ditto in Keppler, bigger of course in the 10mm. Not very crabby-looking.
M35: an open cluster; boring except for the fact that it has a little companion that looks like a globular but is actually a really tight little cluster.

And that is when tragedy struck! Well, when I say tragedy, I mean that M36, 37 and 38 were all behind the house AND that the RA encoder died! J gallantly resuscitated it thanks to his trusty Allan key set. At this point it was after midnight and getting awfully cold, so there was no way I was going to re-align. Thus, to bed.

The next night, in the Grampians

To be honest, it felt like a bit of a dud night. I was using Keppler (Tak128), and it was quite windy so it was a little harder to manage than little Ptolemy would have been. Also, I had chosen some dud objects to try and chase: that is, they were smaller and/or dimmer than I realised, so they were hard to find and/or actually see. Le sigh.

Jupiter looked very average. This was largely to do with the wind; it was hard to get a steady view. Basically pointless with the 6mm eyepiece; 10mm was a bit better, with a few bands of cloud visible. I then tried to find a few things but got frustrated, so J hauled me over to Copernicus to show me some galaxies. First, though, IC418: a groovy little planetary nebula, which looked amazing through the 4mm: that's 450x magnification, J assures me, which sounds like a lot. Galaxies: NGC253 (a large grey smudge of a galaxy, brighter at the centre with a couple of very bright spots, which may actually not be physically associated with it? also possibly a dust lane); NGC288, NGC247, NGC300, and NGC7793 (variations on Grey Smudge, some larger than others). Could not see the dwarf galaxy in Sculptor.

To finish the night I went back to Keppler. I looked at the Large Magellanic Cloud (the detail continues to amaze); Omega Centauri (huge, but I think 47Tuc is still my favourite); M79 (a great little globular); M78 (nebula, not that bright); and, naturally, M42. Which was a happy way to finish the night.

New Year's Eve

We left the Little Desert and traveled over to the Grampians, for a change of scene during the day but still dark skies for observing. It was an horrendously hot day, which cooled off only gradually; and to make matters worse, it was incredibly windy - gusts up to 90kph in our area apparently. This made seeing decidedly sub-optimal; while I was still stooging around trying to get a good view of Jupiter, J announced that there was basically no point in me looking for double stars, because resolving them was going to be a pain in the butt. Tragedy! What was I going to do instead?!

Well, I had planned on looking at interesting things and doubles in Canis Major, so I did check out the open cluster NGC2362; it looked all right with averted vision, with quite a bright centre. I also tried looking at the open cluster + emission nebula of NGC2264, but the nebulosity was so faint through Ptolemy (90mm) that I might as well have been making it up.

I didn't have anything else planned, and was feeling a little weary to be honest (two nights of bed at 3am, and a 40C day, will apparently do that to you). So I decided to let J do all the work and just get the advantage of looking through the 16" Dob. He had a plan for looking at some galaxies in Fornax and Colomba, so that's what I did too. We saw:
* NGC1808, a long faint but obvious galaxy, with a bright centre;
* NGC1851, a tendrilly yet compact globular cluster;
* NGC2090 and NGC2188, both faint smears;
* NGC1792, a bigger grey smudge with a couple of bright spots visible;
* a group of five - maybe six - galaxies all visible within the same field of view (1 degree).

In between looking at those, I did end up going back and playing with Ptolemy. Firstly, I set the Argo to Identify, and played around finding stars: I now know Procyon, Castor and Pollux, and confirmed that Aldebaran is indeed that star in Taurus. Plus, I know where the constellation Lepus is (ish). Secondly, I decided to see what Messiers I could find. Most I had already seen before - M93 (boring open cluster); M46 and M47 (awesome to see in the same field of view, nice contrast with one tight and one loose open cluster); M50 (almost unviewable through the 35mm, being too small/dim). But I did get two new ones to tick off: M48 (small and dim open cluster), and M67 (another open cluster that I do like; it looks like someone took a bite out of the side). I was going to look for more but then my Argo's batteries died! Oh the humanity.

By this stage it was midnight, so we took a final tour of some old faves - 47Tuc, which looked INCREDIBLE and as fake as ever; the Tarantula Nebula, which I choose to think of as resembling a flower; and, of course, M42, whose nebulosity just looked brilliant through the Dob. I had to get a bigger eyepiece to get a better view of it!

The Little Desert, Night Two

Not quite as good this second night. There were a few reasons for this:
1. Mozzies.
2. It stayed hot all night - maybe 23C by 2.30 - so the mozzies stayed around too.
3. More mozzies. They were trying to eat me through my clothes.
4. People. There were a few more people at the Lodge, so there were a few more lights on. Also, I actually knew one of the people! He and his friends came out at about 10pm to have a look, we showed them some of the usual suspects... and then he hung around til midnight. I wanted to have a look at the stuff I'd planned, but it wasn't that interesting, so I didn't feel like I could while he was there....
5. Mozzies.
6. Trying a new telescope. Um. Yes. Have I mentioned our new telescope? It's a Tak FS128 (5") which J picked up through his usual cunning ways. I've called it Keppler... and he's huge, in comparison with Ptolemy (90mm). Coming to grips with the different fields of view in the eyepieces, etc, took some doing, and I'm still not there yet.

What did I look at? Well, we started with Jupiter - of course - and it was by far THE most amazing and awesome view of Jupiter I have ever had, enough to almost make me want to sketch it. The main dark band was blindingly obvious, there was detail to the north and the south, and - perhaps most amazingly to me - the moons clearly appeared to be of slightly different shape and colour. Ganymede was obviously bigger and redder. I was totally blown away - as were the people we showed it to a bit later. We also showed them M42 and 43 - of course! - and it too looked stunning through the 128. In fact I looked at it several times over the night, and it just got better and bigger every time.

To get my mojo back a bit, after my acquaintance left, I took some time to just look up. Keppler has a box disconcertingly like a coffin, which it turns out makes an excellent bench, so I just lay back on it (the ground was awfully sandy) and stared up. Orion was pretty close to the zenith (we were pushing midnight by this stage), and the view was just delightful. I also had a chance to look at a few things through J's Dobsonian, probably my favourite of which was an awesome planetary nebula, NGC1360, with a bright core and a discrete cloud around it. I tried dialling up planetary nebulae to 'tour' on Keppler but it was a bit of a bust with the lights on in the distance.

Anyway, I decided to have a go at some doubles. Using the list of doubles in Orion from vol 1 of The Night Sky Observer's Guide, I had a look at and split: E627; E630; 17-rho Ori (a lovely double, orange and blueish); 19-beta Ori; E664; h2259 (although only the 3.6/10.8 mag stars, not the other companions); h697 (the triple); E697; E701; h2268; E114; E790; E816; 60 Ori and E877. Which, yes, was possibly a stupid number of doubles to look at it one night, but I did stop when I was bored. Additionally, I was practising with the Argo, because I found all of these by pushing the telescope around until the read-out on the Argo was the correct RA and Dec. There was a few times when it wasn't quite right, but overall it was a good way to start getting a handle on using the mount as well as the Argo - and getting myself more used to directions.

We stayed up until just after 2, determined to see Saturn. However, we were flagging fast, so when it was just above the horizon and mushy as all get-out (not coming clear at all, and looking like a weird bulging object as a result), we threw in the towel. Still, it was a good night overall (despite the mozzies), and we're hoping for a few more like it - this time in the Grampians.

The Little Desert, Night One

While it's not exactly a desert, when I say we came here because it's a dark part of Victoria, it is seriously a dark part of Victoria.

My main aim on this first night was to play with my new Argo - a Christmas present - and get used to my Losmandy mount. While I grew to love my industrial green Tak P2Z, it is awfully nice not to have to remember to disengage the tracking and then re-engage.... Anyway, I aligned it pretty easily, and then had a look at Jupiter (of course). Since it's so easy with the Argo I also found Uranus - and even though it wasn't very dark, it was an obviously blue little disk.

I decided to start off by having a go at one of their tour functions, and chose Non-Stellar Objects within 30 degrees of Sirius and a lower limit of mag 8 - since I'll admit that it wasn't exactly pitch-black yet, but I was impatient. First off was M41, a bright open cluster, which looked great. The next few objects were also open clusters, and although they can be interesting enough the joy soon waned: I looked at NGC2345, M50, M47, and M46, skipped a number of NGC clusters, and then gave up and moved on to trying to find triple stars, again using the tour function. This too I fairly quickly gave up on; for my part, it was probably not quite dark enough to be trying to split triples, but it was frustrating in general because the Argo didn't supply mags for all of the stars, nor their separations, so I wasn't sure if I found them or not. And thus I moved on to the 'Bright Nebulae' tour.

First, the Rosette Nebula, around NGC2244. In Ptolemy (90mm refractor), the nebulosity was very faint indeed. However, I badgered J into finding it in Copernicus (16" Dob), complete with brand new filters, and WOW! It looked awesome - we couldn't fit the whole thing into the field of view in the 21mm. It was matched, and bettered in my scope, by M42 and 43, of course - I really do love this time of year - they just looked incredible. Every time I look at the nebula there it just looks brilliant.

I was interrupted at this point in my tour my J's excitement at having found the Horsehead Nebula. He got a H-beta filter specifically for finding this, and was over the moon at spotting it. I'm not as patient as him, so while I could see the band of nebulosity and just pick the 'divot' that marks the famous horse's head, I couldn't make out any detail. The Flame Nebula, however, was waaay more interesting, looking quite a lot like a maple leaf. He also showed me M1, the Crab Nebula - a large, faint, not very crabby smudge - and, a bit later, several faint galaxies around Fornax, including the awesome 'Zorro', NGC1365.

I looked at a few more bright nebulae - NGC2175, M78, NGC1975 (drowned out by M42), and a couple of others that I couldn't really pick - before going back to my old fave, double stars. As with the list of triple stars, I was a bit frustrated by the lack of information provided in the Argo about magnitudes and separation distances for the double stars. I ended up grabbing my Cambridge Double Star Atlas, and looking them up in it to see if it was worth my energy - but some of the ones listed on the Argo weren't listed in the Atlas... I know there are double star catalogues available to download, so I will to investigate those. Anyway, I saw E816 (a separation of 4.4"!! Very proud); Ori60; E838; E877; OE73; Ori68; and E766 (I really should figure out how to do Greek letters, since the E is meant to be sigma...). In doing so I also stumbled on an awesome little planetary, NGC2438, and a totally lovely open cluster, NGC2169.

To finish up the night I tried the non-stellar objects tour again, this time in the incredibly rich area around Carina. I skipped most of the open clusters, but looked at Omega Centauri (always breathtaking, and stupidly detailed); NGC2808 (another globular, this one quite faint); the Gem Cluster and Jewel Box (open clusters I will make an exception for); Centaurus A (a faint galaxy with what appears to be a split in the middle); and the seriously cool Ghost of Jupiter (another planetary nebula - I love it).

We packed it in around 2.15, with the moon rising: a crescent, it was so yellow it looked like a banana. If we'd hung around a bit longer we could have looked at Saturn, but my goodness it got cold. From complaining about the heat in the day, we ended up as rugged up as we've ever been while observing. Can't wait for tonight.

Transits

We've dragged the telescope out twice in the last week or so, but only briefly. We haven't really had much summer, yet, so it's been quite cloudy and quite cool at night! Anyway, this may be my favourite celestial time of year: Jupiter still visible for a while in the West, and Orion visible at a really decent time in the East. Whee!

Both times we've had a look at Jupiter we've spied shadow transits, which I think is pretty amazing given they were both haphazard viewing opportunities. The first time it was Europa, and tonight it was little Io. Tonight in particular the shadow was a really dark circle on the disc of Jupiter - very obvious indeed.

Also today, the nights officially start getting longer again! Gone are the days when I was just all about the sunshine, baby. Now - ah, now, I get to be totally conflicted. Fun!

The Warrumbungles, #1

When we left Lostock and the Ice in Space camp, we headed west to Coonabarabran. The point was to visit the Australian Astronomical Observatory, and maybe get some viewing in. The AAO is cool to see - I especially liked the world's-largest solar system replica: the dome of the AAO is the sun, and the rest of the planets are spaced out, at appropriate distances (over 100km), along the main routes into town. The visitor's centre is a bit... um... tired.

We stayed at the Warrumbungle Mountain Motel, which is for sale if you're interested. I think our motel room was bigger than our house. And we were the only ones there the first night, so when the clouds finally cleared - hurrah! - we dragged the scopes out onto their golf course (!) and settled in for a couple of hours. We'd even been sensible and prepared a thermos of tea in advance.

The moon was out at as a little crescent, which was really lovely to see - especially as it got darker and the whole disk was lit up by earth-shine. It formed a picturesque triangle with Venus and Mars, both naked-eye visible; Mars was very red to the naked eye, and in my 6mm, although it was a bit hazy. Jupiter, on the other hand, was looking spectacular; I could clearly see a white band of cloud in a roughly similar position to the dark band in the opposite hemisphere. And, excitingly, we saw Neptune! - definitely through J's scope, and I think through mine. Hard to see through J's, for me, because it was near the zenith - so I was on tiptoes to reach the eyepiece.

J had a good night of chasing Messiers and galaxies. I had a good look at NGC247 and 253, both of which were (to me) surprisingly large, and bright, although they did both still look basically like cigars.

I was pleased to be able to hunt down a couple of doubles in Capricornus, and M30, a globular cluster which looked bizarrely like a molar. The first double I spied was epsilon Cap, with a bright white primary and a very faint companion. The second was an absolute highlight: alpha 1-2 CAP, so called because alpha 1 and 2 are a binary (I'm pretty sure), both beautiful yellow stars, and they both have a separate companion. I found one companion, but not the other - it's only 7" away from its primary, and it wasn't great seeing, so that's not a huge surprise.

I finished up the night hunting down M4, near Antares, because the rest of the sky got cloudy... that was around 10.30pm. I'm very proud that I now know Capricornus.

Lostock: three potential nights of all-out viewing...

Ice in Space Astro Camp: three nights, at a remote Scout camp, with ~100 keen amateur astronomers+hangers-on. What could possibly go wrong?

Thursday night: some sucker holes!... but cloudy. Also, rain.

Friday night: cloudy.

Saturday: the sun was out enough that a dude had his solar scope out, and we wandered over to be bothersome and have a squizz. I saw prominences! And the surface of the sun! Without my eyeball boiling!! ... I might be in love...

For all that it was annoying that we didn't get to observe every night, the camp was awesome. There was a lot of telescope-ogling, and deep discussions about eye pieces. Our cat's perch chairs drew a lot of comment, as did J's scope. The fact that we both have scopes and I wasn't there under sufferance also attracted notice, which I thought was a bit sad; the number of times I basically got asked if I was happy to be there, and then I pointed to my scope and said I got mine first.... There were a few other women there with scopes, but it was by and large a male gathering. It was neat to see a few blokes there with their kids, though, having left mum at home.

Anyway, we did observe on Saturday. Sitting at dinner, we kept sticking our heads out to look at the sky - hopefully noting the holes in the clouds - with the constant refrain being "I've seen it come good from worse...". At one point I realised I could see Jupiter, and I ditched whoever I was talking to and hared it back to our camp. I figured I would at least have a look at it, if nothing else. I caught Venus - lovely little crescent - and Jupiter, and then, all of a sudden, looked up: it was clear! The clouds were almost entirely gone! And wow, the whole camp... changed. Red lights zipping around the place, people excitedly discussing their favourite objects, arguing about collimation: it was cool. We had a little crowd in our area, what with two SDMs next to each other. I got a little frazzled because I couldn't figure out the constellations - I only know Scorpius and Sagittarius in the spring sky! But a couple of people showed me some interesting things, which was really nice of them.

I saw the globulars NGC6388, NGC6397, and NGC6723; BrsO-14 in Corona Australis, a binary with two small white stars; B86 and its accompanying dark nebula - don't think I've ever consciously seen a dark nebula before (the Coalsack doesn't count...); M27 - the Dumbbell Nebula! and possibly Barnard's dwarf galaxy. When I discovered that we could see Pegasus, I checked out the binary that is Matar, which has a bright yellow primary and a faint white secondary. Also through my scope I saw a few other random globular clusters, the Pleiades, M79, and we managed to stay up late enough (bed at 2am!) to see the glory that is Orion (I've missed him!).

Someone set up binoculars near us, through which I finally saw the Andromeda Galaxy. It was... a disappointment, frankly. I couldn't see it naked-eye, probably partly because it just doesn't get that high even in NSW, and through the binos it was just a blob. Still: furthest-away object you can (theoretically!) see naked-eye, and closest galaxy to our own. Nice to cross off the list :)

I also got to have a look through Rod's 20" scope, which he set up next to ours. It required a ladder to get to the eyepiece, and a trailer to bring it to the camp. I saw NGC1365 - a galaxy -which is apparently one of Rod's favourites, and was indeed spectacular. The Saturn Nebula is a weird green colour and does indeed look like Saturn, and 47Tuc was breathtaking. My favourite, though, was being able to see three out of four galaxies known as the Grus Quartet - the other one was just outside the field of view.

All in all, it was a seriously awesome night of viewing, and was a great way to finish the camp.

On top of a mountain

We've just got home from an almost entirely astronomical holiday through NSW, precipitated by the annual Ice in Space Astronomy Camp. We went to the Deep Space Complex at Tidbinbilla, and came home via the Australian Astronomical Observatory at Siding Spring and the radio telescope at Parkes. We also managed to observe for four nights out of ten, which probably isn't a bad hit rate!

Our first stop was at a lovely B&B between Thredbo and Jindabyne. It was kinda clear the first night, but we hadn't set up the scope so we decided to be lazy. The last night, however, was glorious (how glorious? LMC and SMC very clear to the naked eye) - and we'd found a great spot for observing just up the road from our accomm, very flat and away from the few house lights in the area. Paul, the manager of the B&B, had mentioned he's been thinking of trying to organise astronomy groups, so we dragged him out and showed him some of the sights, and talked to him about telescopes a bit too.

It wasn't a night for working through a plan, not least because we only set up my scope so J and I had to share. So we had a look at Jupiter, who was brilliant, and then J managed to find Uranus! Which Paul didn't think was that impressive - just a blue smudge - but I was wildly pleased.

We had a look at some Messier objects, largely to show off: M8 (Lagoon Nebula), M16 (Eagle Nebula), M17 (Omega Nebula), M20 (Trifid Nebula), M22, M23, M24 (Star Cloud), M25, M54, M69, and M70! - and NGC6652 because it was in the neighbourhood, as well as 47 Tuc. I am still not that enamoured of open clusters for their own sakes - many just don't seem to have outstanding features, for my money - but I adore globular clusters. I don't really know why; I think it's that looking at them for a while, you can start to pick out detail - slowly but surely. I love all of the nebulae we saw, and the Star Cloud blew me away: I was looking through the eye-piece as J star-hopped via the Rigel, and it just suddenly appeared. Awesome.

We also had a go at photographing the Lagoon and Trifid Nebulas, and I will upload some of those when I find the camera amongst the end-of-holiday detritus.

An experiment

That's the Lagoon Nebula (M8), from our backyard: iso 800, 30 seconds. Check out that colour!!

A little Jupiter: iso 800, 1/800 second. Bit sad you can't see any moons... longer exposure, and darker skies, required.

The Jewel Box - a lovely little cluster near the Southern Cross: iso 800, 5 seconds. Not quite in focus, but you can still make out some colour.

Cr316: J's favourite little cluster, in Scorpio. Iso 800, 5 seconds.

Spring apparently means clear nights!

Well, this is Melbourne, so when I say 'clear nights' I really mean 'one clear night amongst the many murky ones.' Nonetheless: today it hit 20C for the first time in many months, there were lovely clear blue skies for most of the day - I sat outside and read! - and it stayed clear for the evening.

We started off looking at Venus, which was a delightful thin crescent. Then, waiting for the sky to darken at least a little, over to Alpha Centauri; split beautifully.

It didn't ever really properly darken tonight; probably we didn't leave it quite late enough. Anyway, Antares (the anti-Ares, ie Mars; cool!) was a lovely reddish colour, and I discovered that beta Scorpius, aka Graffias, is a double: a pair of whiteish-blue stars. Another of the Scorpius stars is also a double, but I did not split it - although it did look quite bulbous, so perhaps I was close.

Close to Scorpius is M7, which I managed to find all by myself - at exactly the same time that J found it through Copernicus, which was quite funny. It's a lovely open cluster, with a nice scatter of stars. Close to it is M6, but I did not manage to find it, which made me a little grumpy. To make up for it J pointed me towards Cr316, which I'd been thinking of finding anyway. It too is an open cluster, but (optically at least) much tighter than M7. Through the 35mm lens, it was quite spectacular.

Testing out just how good my eyes are, and how light the sky was, I next looked at the star G Scorpius, because next to it is a globular cluster, 6441: very faint from here, and you'd just assume it was a smudge if you weren't looking for it. In fact, my next target - M22 - I didn't even see even though I was looking for it. I got - ahem - a little petulant; J had a look to see where I was at... and it was there, in the eyepiece, I just hadn't noticed. Too faint!! - it's another globular cluster.

Really, all of this was a prelude to the main event, which was Jupiter. In order to get the earliest view possible, J decided he needed to do some gardening: bits of a climbing rose were waving about too high. Up a ladder, with secateurs, with only a red headlamp for light... awesome. Anyway, it was a totally classic view of Jupiter tonight. All four Galilean moons lined up, nicely spaced out. Jupiter itself still looking kinda weird with only one dark belt of clouds.

It was a great night's viewing, in all, and not even too cold. Also, not many insects! I'd like to observe in conditions like this all year rounf!

Clear skies are here again

It's been a while. Tonight, for the first time in a while, we had both clear skies and the energy to do something with them. Here's hoping Melbourne gives more of the same! - after the rain that's forecast for the end of this week, in any case.

Anyway, given the skies and the fact that even when the sun was barely down I had a good view of crescent Venus, I messaged some friends just down the road that they should bring their kids over for a look - I'd been meaning to do so for ages. They promptly arrived with two in tow, the eldest being sensible and staying home, feeling sick. We trooped out the back and had a good look at Venus, and Mars - just a blob these days - and had a chat about planets. Then, because the stars were coming out and they were enthusiastic, J decided to show off and show them the Jewel Box; I met that with Alpha Centauri, which split beautifully and particularly excited the youngest. All of which was very pleasing.

We went back out a few hours later, because it amazingly remained clear. Sagittarius and Scorpio are back to being high in the sky - it's like seeing old friends! It wasn't particularly dark, but J hopped around some clusters in the two - M4, M6, and M7; M20 and M21 - the Triffid, looking pretty awesome even with the light pollution. Right when we thought we were ready to pack it in, J had a last look all round the sky. And there, my friends, at -2.5 mag, was dear old Jupiter! I can't tell you how ridiculously exciting it was to see it hanging there so brilliant. Io, Europa and Callisto were nice and obvious, as was the one dark band of clouds that it has left. J thought he might have caught sight of the Red Spot, but I am unconvinced. I stared at that disk for quite a while before achey eyes drove me inside.

Haze, clarity, haze

Stinking hot day. I didn't have much hope for the evening because there was a lot of cloud just on sunset, but it did clear - mostly, anyway. In astronomical twilight, I went and set up the scope (mostly all by myself - with the new mount - dead exciting, if a bit hard); found Jupiter, but it was pretty hazy off to the west. So I saw it, and I think four moons, but it wasn't very impressive.

Next, swinging around, I tried for the Orion Nebula - and found it, but again it was just too hazy: there was no nebula! Also, still not that dark. This was a bit sad for K, who came out in the dark and mosquito-infested-ness only to see just a couple of stars.

Anyhow, went back inside for an hour or so. Then, ta da! It cleared! So out we went again. Orion, this time, looked totally spectacular - so K, and D, both got a good look, and I think they were impressed. Then around to the Pleiades, which looked pretty good. J tried to find 47Tuc, but to no avail - clouds were coming up in the west, and it wasn't quite dark enough anyway, I think.

The last thing we tried was M41, we think; it was an open cluster, and it was roughly where J was looking for it last week in Melbourne. Certainly found a cluster, anyway. By this stage the clouds were coming in, as was gauzy haze, and the mosquitoes were getting worse. So we packed it in.

Mount and mosquitoes

A little while back J caved, and decided that actually he'd quite like his tripod back, and the telescope would do better on its own, proper, mount. So he ordered one, and six weeks later it finally arrived. Huge darn box for me to lug home from the post office.

There was a bit of angst over the setting up, and we're still not entirely sure it's exactly how it should be. But it's very stable, so it seems ok. And I love that there is a little tray between the legs for putting eye pieces on!

Last night, a lovely evening, we were too stuffed to take advantage of it. Tonight, there are a few clouds around; we went out for a little bit, but were soon driven inside by mozzies. Before that, we had a quick look at Jupiter - very low on the horizon and quite atmosphere-muddled. Then Orion, but really it's not dark enough yet. Finally, because I noticed in Stellarium that they were close to Orion and Sirius and therefore should be easy enough to find, J found the open clusters of M41 and M47. At that point we caved before the might of the insects and decamped inside.

I love the mount, though. It's lovely and wooden, and suits the scope far more than the grey metal of the camera tripod ever did - a very important consideration, of course.

Late night Ballarat viewing

We did view briefly on the night of Boxing Day; we showed some friends the moon, and they were suitably impressed. We didn't get much more viewing in - we saw Orion, and 47 Tuc, both of which were of course awesome; but then the clouds came up.

Last night we were utterly tuckered out. We convinced ourselves there were some clouds around.

For tonight, our last with the clearer skies of the Rat, we prepared well by napping in the afternoon and not having too strenuous a day. Very important, this sort of preparation. Happily, it wasn't as cold as the last few nights; sadly, for us, the moon is enormous (86% full, according to my adorable widget) and was hanging bulbous and annoying right near the Pleiades.

Anyway, we started by looking at Jupiter - very low in the sky, in fact just about disappearing behind the roof of the house. It wasn't an awesome view, but most importantly for me I'd realised that Neptune is very close to it at the moment. We're pretty sure we found it; the blob of light certainly looked like a disk, rather than a point of light, just as Jupiter's moons (let alone Jupiter) and Mars resolve. There was no blue/green colour, because it was too low to the horizon; it was yellow/red instead. For the same reason, Jupiter was an awesome fake yellow/orange colour, although it was impossible to resolve it properly thanks to the atmospheric issues. ETA: apparently Neptune is currently mag 8, so I'm pretty pleased at finding it, it being so close to the moon and all.

Next, we tried checking out some stuff near Canis Major. First up, M41, an open cluster. I'll admit here and now that I am not usually wowed by open clusters (in my vast experience of them). This one was pretty enough... but it just looks like a particularly dense clump of stars. Which it is. Nearby, we looked at Cr121 - where Cr, according to my trusty Pocket Sky Atlas, stands for Collinder, presumably the dude who catalogued it.

Swinging around we amused ourselves looking for 47Tuc, and although the sky was still washed out it was still all tendril-y looking. Swinging back, J got a bit ambitious and tried looking for M44 - the Beehive. We didn't find it - too low, and therefore behind the trees from our position. We did find some cluster, but we have no idea whether it has an official designation.

The Orion nebula, as always, looked good - although it too was a bit washed out from the moon. Despite that I think I'm picking up new details every time; I don't remember noticing a star below the Trapezium before. And M43 looked quite obvious too. J picked up the Small Magellanic Cloud in the binocs, as well as various other bits and pieces. I had a quick look - I'm not very good with binocs, at least partly thanks to the specs - but in my wavering grip even I could see M42, vaguely, as well as a couple of the open clusters.

Finally, we wreaked vengeance by looking at the moon - remembering this time to put the neutral density filter on, although to be honest I still felt blinded. Tycho and Copernicus were both in full view, with their respective ejecta very obvious; it was a brilliant sight.

Overall, we've had good viewing up here. It's going to be weird to go home to very obvious light pollution.

Back in the saddle...

or on the 'scope, as the case may be.

As my friend Gina noted the other day, the blog has been rather quiet of late. There are a few reasons for that. Firstly, the late Nov/early Dec sky - earlyish in the evening and especially from our yard - is boring as batshit. Second, there have been lots of cloudy nights recently, and when there have been clear nights... well, third, we've been awfully tired.

Anyway: tonight it was beautifully clear, we're not too tired, so I pulled Ptolemy out and there was Jupiter. Looking lovely. I didn't quite get out it in time to see the moon - it had disappeared behind the trellis - but Jupiter had four moons looking lovely.

Then, I turned around, and presto! there was Orion coming up out of the foliage, and despite a dirty big streetlight (grr) it looked good. And there, my friends, there was the Orion Nebula, M42, looking awfully shiny and nice. The Trapezium (four stars that very obviously form a rectangle) looked brilliant, and with averted vision the nebula itself was looking like a lovely butterfly. I was originally looking through the Ethos, then swapped to the TeleVue for a closer look. And it was great.

J played with his new toy, which arrived today: Fujinon 10X70 binocs.

Can't believe we got to view tonight

... given that the whole day it's been raining, and raining, and raining.

It's the first night for viewing all week, basically - clouds have come in every night - except Thursday, when we had some friends over and showed them a fingernail of moon (first time for all three!) and Jupiter + three moons (also first time!), which was fun.

Tonight, given we're both awfully tired, we just looked at the moon and Jupiter. J decided to have a go at crossing off one of his sketching goals - from the Lunar 100 - the result of which is this:

He's not sure whether he likes it without the square border. What do you think?

It's number 20 on the list. We like lists. I downloaded a list of galaxies to try and view, the other night. One for dark sites I think.

Jupiter was pretty easy to see; it's clear that in a few months it's going to be completely gone from the night skies, at which point I may cry. When I first pulled it up, all four moons were visible, with two very close together and only just separate. I wasn't sure if they were coming or going... until all of a sudden two became one, which answered my question. Stellarium informs me this was Europa and Io, and that if I'd been just a little more patient - or a little less tired - I would have seen them come apart again quite quickly.
