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.

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.

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.

November has boring evening skies

We've had a couple of viewings of Jupiter, but nothing spectacular. Frankly, November is seeming a bit boring here in the bright urban areas. Plus, we've had some cloudy nights.

Tonight J dragged Ptolemy out and played around with the polar alignment, figuring out exactly where celestial south is from our backyard. He also had a look at 47Tuc, which looked quite good despite it being quite bright to the south. I could see a few stars to the left and bottom; not sure if they're in front of the cluster or part of it.

On to Jupiter, and hey! a shadow transit! Very exciting to see. Just three moons, all in a line. Could see a bit of detail on the planet's disk, the pole looked darker and the two main bands certainly had some texture.

We came back inside and sat around for an hour or so, waiting for Orion to make the sky interesting... and then there it was! We could see the Orion Nebula (M42) from our backyard! This is very exciting. Sure it looked better from Ballarat, but that we can see it clearly and with some detail, even with just a cursory glance, is very encouraging. Four stars were obvious in a tight little cluster, in the middle of the nebula. Expect to see M42 get bigger in that tag cloud over the next few months. I'm also looking forward to looking at the other stars of Orion. Interestingly, the nebula filter didn't seem to help that much. Forgot to look for M43, though, I just realised. Oops.

That's what you get for impulse buys

Seems like a boring time of year as far as the sky in urban Melbourne is concerned; or maybe that's because we're not staying up late enough, so the sky isn't getting dark enough.

Anyway: the impulse buy was the Telrad. Turns out it's not particularly easy to mount on the Sky-90, which is a shame. To set that right, a box turned up today, to receive which I was required to stay home: it contained a Rigel QuickFinder, which is exactly the same idea as a Telrad, just a bit smaller and easier to mount on Ptolemy.

Unbeknownst to me, J also decided to add an Extender-Q to Ptolemy. Essentially this corrects the Sky-90 for looking at the moon and planets, and gives an extra 350mm of focal length. Now, with the zoom, I have 265x max magnification, though it will take a very steady night sky to get to that level. It does make the scope look totally lopsided, but it also made Jupiter HUGE. Which was cool... pity the atmosphere was so whacked, at least partly from the heat.

We decided to play with the Rigel by choosing a couple of Messier objects in Sagittarius to try and find. First we tried to find M70; pretty sure we got the right area, but it must be too dim; M69 was also too dim, and I'm not convinced we got the right area. M54, however: bingo! Right where it should have been - a very faint globular, but definitely there. Then J realised that with Achenar pretty high up, one of his longed-for targets should be visible... and there, lo and behold, was the glory that is the globular cluster of 47 Tuc. This is one of the brightest globular clusters in our sky, and it looked awesome even in our light-polluted backyard.

All up, a good night's viewing.

Too hot!

It's Melbourne; we complain about the weather almost as much as Brits do. It's compulsory in this town.

Fairly bright to the south even at 9pm, so not a whole lot of interesting viewing. I got in Jupiter, which was looking pretty good - two moons either side close in, two either side further out. A third band, to the north of the disc, was obvious.

J had flaked in bed because of the heat, so I decided just to be impulsive and simply started turning the adjustors. I was doing this with the 6mm eyepiece, so perhaps not the best for just randomly roving the sky, but kind of fun nonetheless. I didn't find anything interesting - except for a couple of quite red stars - but it kept me amused for a few minutes.

A few days ago...


... it was clear enough to have a quick look at Jupiter, but really not much else; there were skating clouds, and a haze that made it even brighter than normal because the lights were reflecting back off. Did I also mention the mosquitoes?

It's weird to notice the sky having moved around since we started on this caper. Where is Scorpio going?? Why isn't it stable??

Hard. Core. With frog chorus

We had planned to go camping this weekend: take the scope out to some dark site, stay up really late, it'd be awesome! Yes, well, then we realised that it's a full moon this weekend. Great. Also, the weather forecast just got worse and worse.... So we decided to visit the parentals in Ballarat, because that is at least a bit darker than Melbourne, and if the weather was bad it wouldn't be a disaster.

So we came up yesterday, on a scorching afternoon - where were those thunderstorms? - in time to have dinner with some good friends of J's parents. As they were leaving (after there had been lightning, and a short but violent rain storm), the clouds had cleared somewhat so we dragged the telescope out to show them (and especially their two young kids) the moon - enormous and very bright - and Jupiter, which was a real highlight. Could only see two cloud bands, the brief time I looked, and at first it looked like there were only three moons visible. On closer inspection, the fourth was there, really close to Jupiter itself. Which at least one of the kids could definitely see and was very excited about.

The hard core aspect of this weekend was the setting of the alarm for 4am this morning. And that we actually got up when it went off. Admittedly, I hadn't slept that well because it was hot. We crept outside - trying very hard not to disturb other sleepers - and set Ptolemy up on the side away from the moon, which was only just disappearing into the trees (it was very yellow indeed).

Our first target was M45 - the Pleiades. It was obvious naked-eye, and quite pretty (could count seven stars). It was pretty cool through the scope, although I didn't know what to expect so I wasn't entirely sure I was seeing it all. I look forward to seeing it at a really dark site.

Next we swung up to Orion, which I haven't seen in ages! It will be nice to look at it in winter. J found the Orion Nebula in the sword - M42 - which was just amazing. I think it was heaps more impressive than the Lagoon, to be honest. Its shape was quite distinct, and the Trapezium Cluster of stars in the middle was very obvious and added a beautiful highlight. It was very, very exciting. Additionally, I thought I could see some nebulosity around a star very close to the nebula - turns out this was M43. Go me.

Finally, we moved the scope so that we could Mars above the trees. I couldn't focus on it very well, mostly because it wasn't very high above the trees and there was some haziness, but it was still a very obvious red disc. It was much bigger than I had expected, and that's when it's a very long way away; I can't wait for when it's closer and we'll be able to see some detail. Of course, that won't be for a few years....

We stayed outside for about 40 minutes. Clouds were coming through fairly frequently, and by the end of that time it was pretty much entirely clouded over. I did get another good look at M42, which pretty much made my night (day?). So I think it was worth getting up at that time, although I doubt we will make a habit of it.

Approved


God clearly approves of our new hobby. All afternoon - clouds. I came home early from uni partly because I didn't want to get stormed on. We get out of pilates... and the sky is completely and utterly devoid of cloud.

Of course, we still had to deal with Killer Mosquito Brigades. It's warm enough I could have been outside in a tshirt, but I wasn't; I like my arms without welts.

Moon was lovely: Copernicus is hugely impressive, of course - I love it more every time. My new discovery tonight was Schiller, an elongated crater that looks really bizarre with half of it full of shadow. I also quite liked this crater, even before J drew it:

Jupiter looked pretty normal. Seeing was entirely average from the backyard.
