ASV Messier Night

This weekend we went to the annual Messier Night held by the Astronomical Society of Victoria, at their dark site a bit out of Melbourne. We arrived mid-afternoon; staked out a spot, and set up our enormous (brand new) tent in the camping area. We set up the PST in the observation field; there was another solar scope somewhere else, which I didn't have a look through. We had a number of people come past to have a look, and they were pretty impressed, which was of course gratifying. The sun was looking awesome: one sunspot by itself, and a 'little' clump of solar spots in the other hemisphere. There were some cool prominences going on too, one in particular that was quite feathery. I didn't actually get much of a look, but that's ok. Hopefully the clouds will stay away in Melbourne a bit more, so I can get it out here.

We set up Copernicus and Keppler before having some food; both got some comments from other astronomers out setting up. People were mostly curious about why our lovely 128mm Tak was in the observational field rather than the photographic.

The night itself was well organised. The site is great - a bunkhouse and toilets, and they had a Lions Club out there with food and drinks - and they had a number of people giving short talks about different aspects of astronomy, as well as someone later in the night giving a talk about what was visible. I hadn't expected that there would be so many people for whom this was a completely new experience; the ASV must have advertised the night outside of the Society itself. It was a good idea, I think: I heard someone very excited about being able to borrow one of the ASV's scopes when they got home. As a consequence of this, though, there were a lot of people wanting to have a look through the various telescopes that were set up. Happily, I had no plan for the night other than find Saturn, and use the Argo to go a tour of the Messier objects.

Early on I had a look at the Pleiades - which just never looks good through a scope - and the Hyades, which I like; it forms quite a distinct triangle. I tried to split Procyon on discovering that it was a double (I was trying to figure out the stars on Canis Minor), but the atmosphere was pretty turbulent, and I have no idea what the mags of the stars are. It finally got dark enough that M42 looked awesome, which was of course a delight.

I had a look at a few Messiers - so many of the open clusters are just dull, and I didn't spend much time on them. Saw M78, that lovely little nebula in Orion, with two associated stars. Then Saturn was high enough above the trees to make it worth having a look - at least if it's something new - and I think, over the night, maybe 40 or 50 people had a look at it. There were some people who had never ever looked at a planet through a scope, and they were seriously impressed. It was a lot of fun, actually; I really enjoy helping people appreciate the night sky. Over the rest of the night I also showed some people Omega Centauri and 47Tuc, impressive of course, and then I finished with M42 - of course - and showed a few people that, too, which they all enjoyed.

It didn't get as cold as I had feared, so the freezer suits never made an appearance (happily!). I made it to 1am comfortably, but from there I started to fade, so packed Keppler away and just had a look through Copernicus. Early on I had looked at the Tarantula Nebula through J's new 20mm Nagler, and it looked spectacular; so did 47Tuc, and an amazing planetary nebula with a hole in the middle. Later in the night it was dark enough to see the Horsehead Nebula, and I think this time that I really did see it, which is thrilling. The Flame Nebula was more interesting, though. Also, the Sombrero Galaxy: seriously, seriously cool. The dust lane was clearly visible... it may be one of the most interesting galaxies I've seen, actually. Just before bed we had a look at the Spindle Galaxy - which I didn't look at long enough to see the elongated ends - and the Ghost of Jupiter, which was just mush. Finished on Omega Centuari, which was an adequate substitute for Orion. I guess.

In the tent by around 2am.

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.

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.

Christmas night

As predicted, the telescope has given J an easy way of buying me presents. I 'unwrapped' (don't ask) a 17mm eyepiece, which is mostly mine, and a 35mm, which is partly mine and will be mostly J's when he gets a certain something next year (again, don't ask).

Being in the 'Rat, we rather excitedly watched the sky off and on throughout the day, in between eating and napping. It stayed clear, so after we recovered from dinner we took the scope out. One problem: J, in his forgetful optimism, had poo-poohed my query of whether to take my beanie and/or gloves. Turns out that actually, yes! They would have been a good idea. Fortunately after standing out there freezing in a jumper for a little while, my mother-in-law rescued me with gloves.

It was a glorious night. Of course, it wasn't as dark as it could have been, what with the half-full moon that was casting extreme shadows. Looked at it for a little while - hadn't added the filter, so I was half-blinded when I looked away. But it did look awesome. I could see the Montes Appeninus really clearly; it's the first time I remember noticing them. There was also an awesome large crater to the south, with two smaller craters within it that looked fantastic, the rims just catching sunlight. J thinks it might have been Clavius, but I'm not convinced. I didn't check last night because my hands were too cold.

After recovering from moon blindness, we turned on Orion - and the nebula looked just amazing. We played around a bit with the different eye pieces, experimenting with the wider view and the close-up view. For me, the wider view didn't do that much; it's kind of cool to see more stars, but since the other stars in the sword are actually little clusters, it's not like you get a line of stars like you see naked-eye. Anyway, M42 itself was breath-taking. We also saw a satellite zooming across the sky, which was very cool.

While J was looking at the nebula, I was looking around the sky. Off a bit to the north was Sirius, of course, and a series of stars that looked like they just had to be a constellation. Oh, of course; after looking it up they turned out to be Canis Major. Exciting to recognise it!

Next we swung a bit west, and J set himself the task of finding 47 Tuc, that lovely globular cluster. He found one, which we had a look at, but it was too faint to be the right one. At that point I got out the map and reminded J exactly where he was meant to be looking. Then we found it, and it was incredible. With the zoom lens, while it got a little fuzzy you could also see more detail in the centre - lines of darkness, and zillions of pinpricks of light. With the wider view we could see the tendrils that extended out a fair way from the central blob. Very rewarding.

I'm very keen to see the Magellanic Clouds (also Andromeda, because, hello! They're really outside our galaxy!). We'll never see them from home, so it was a good chance to try from here. Sadly, I could only get the vaguest hint of the Small Cloud, naked-eye; there was the moon, and Ballarat puts out a surprising (and annoying) amount of light pollution. By the end of our viewing session, though, the Large Cloud was quite obvious naked-eye, so I declared we should have a look. Of course, it was a bit disappointing, because it's not like looking at a nebula, although I originally thought it should be. Instead, it's a dense but not that dense conglomeration of stars, and I'll have to do some studying of the map to be able to pick out genuine features. I did see a globular inside it, too, though.

Finally, we finished the evening by checking out the Pleiades. We started by looking through the 35mm, and really that was the best option - it's such a huge group of stars that anything smaller doesn't really do it justice. So I'm sold on it for objects like that. It really is a delightful cluster.

Here's hoping Boxing Day delivers clear skies, too. Because I'll be starting with gloves this time.
