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.
