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.
