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.

Combing Puppis

It worked well for J having a list of Messier objects he wanted to look for, so he could mark them off. Just having the book to look at with Crux hadn't worked as well, so I chose a new constellation to check out - Puppis - and made myself a List. I ended up working on it both Friday and Saturday nights.

Puppis as a constellation was, or is, a part of a huge constellation: Argo Navis. Puppis is the stern - Carina is the keel, Vela the sails. Puppis was directly overhead on Friday and Saturday, which in theory was good because it's the best seeing but in practice made it bloody hard both to find things and then to look at them properly. It also didn't help that it's not an especially distinguished constellation; I had to keep reorienting myself with regard to Sirius and the rest of Canis Major, because I just couldn't figure it out otherwise.

I'll say up front that I didn't find everything I wanted to. Partly that was a tiredness issue - because we were doing a lot of other things, as well as observing, we weren't nearly as fresh as is optimal come dark. It was also an issue of navigation. I'm still finding this quite difficult. That most of our maps are designed for the northern hemisphere does not help; nor does the fact that the maps have different scales - often it's different for different maps in the same book - so, when you're starting out spatially challenged, it's an added degree of difficulty. Nonetheless, I did have fun, with the odd moment of frustration.

Puppis, for a scope the size of Ptolemy, is all about the double stars. So, I found and split k Puppis; 5 Puppis (a nice reddish tinge) and 2 Puppis. I don't think I found R65, which was disappointing because it's a triple. I think I found Sigma Puppis, but I'm not convinced - I saw a reddish star with what looked like a faint companion, but I'm not sure it was the right spot.

Other than those, I also found M46 and M47 all by myself (and didn't that just get a victory dance from yours truly), and another open cluster in M93. NGC2451 is yet another fairly diffuse open cluster; NGC2477, however, is a very cool, fairly faint, kind-of teardrop shaped cluster which I really liked. And found all by myself.

Again, we had friends out with us both nights; D and K, and also A&G. So we had to turn on a good show: Mars, Saturn, Orion Nebula, the Jewel Box, (I looked at all of these both nights, I think - old reliables!) and just to show off I showed what Acrux looks like as a binary. Which was fun.

J was chasing Messiers again. It was dark enough that the Large and Small Magellanic Clouds were quite obvious to the naked eye when it wasn't even what I would call especially dark, so he aimed at the Tarantula Nebula which was awesome. He found the totally amazing Leo Triplet, too - a set of three galaxies that can be seen in the same field. And we looked at the Beehive through the binoculars. Well, I tried anyway; I really am not good at holding them in place. Glasses don't help.

Again, it was an awesome weekend of viewing. We didn't stay up as late as we would if it had been a dedicated astro weekend - don't think we saw midnight either Friday or Saturday, although we did hear all of Mark Seymour's gig on Saturday! But given it was mixed with riding, and lots of food, and lots of people, I think we did well.
