Obs report 8/1/11

Last night was the first club night for the year. Skippysky forecast was coudy at the 10:30pm image and clear by 1am image. I was going anyway.

As I left home the sky was already beginning to clear so I had hopes of a good night. As I approached Willunga there was a thick cloud bank pearched on top of the ridge. I was driving through cloud over the top of Willunga hill, things didn't look so good any more. I arrived at the site with a thick covering of cloud.

Not to be detered we waited and by about 11pm the sky was clear enough to get a look. I went straight for the 'elusive' NGC1808 & 1792.

10" Lightbridge, 26mm & 15mm EP

NGC1808 & 1792
I hopped around through now familiar star paterns to where it should be and there they were both in the FOV of the 26mm. I put in the 15mm for a closer look.

NGC1808 positioned inside a trpaezium shape of four stars. It appeared brighter in the center and overall had an elongated oval shape.

NGC1792 had a more even brightness over the whole galaxy and was slightly broader on its short axis.

I couldn't see anything in the way of finer structure but I was just happy to find them.

M42
First look through the 10" from a dark site and I was not disappointed. I could see just as much more again as the 10" revealed from home. The big bright wings I could see from home now came around to complete the loop. Inside this area was clear but fainter nebulosity. Fine structure could be seen throughout.

With the 15mm I caught brief glimpses of the E & F stars in the trapezium.

SMC
I took Patrick's SMC charts for a spin over the SMC. They proved very useful to identify areas of interest. I didn't get past chart 1 there is so much to look at. I didn't take detailed notes but will certainely be back.

About 12:30-1am the clouds came back, we waited for a while but there was no sign of it clearing soon so we packed up. On the way home it was clear sky once I was back over Willunga Hill but the wind was terrible. i was too tired to set up again at home.

Hi Michael, glad persistence paid off and you got some viewing in.
Were you able to see the Running Man nebula in Orion? I haven't seen it yet- I'm guessing it's one for a dark site. Thank you for the report.

Re: the Running man (NGC 1977) I got this from my backyard in Colac which has some LP and some transparency issues. The UHC filter helped.
I found the technique is to let you eye drift from M43 toward the line of 3 stars, the brightest part of the neb is closest to M43. The actual man shape is quite hard but with resaonable skies a 10" should get it. Also keep trying, I tried for several nights before I was confident I was seeing it, apparently with seeing, practice makes perfect!

Skippy skies, a knowledge of local weather patterns, and a good gut feeling are invaluble in our hobby. Sounds like the stuff of a satisfying session.

Good to hear that you had a good night, Michael. I find 1808 and 1792 quite elusive as well, I think because they are a far way from the brighter stars of the constellation. Also at this time of year they tend to be in Dobson's hole a fair bit of the time. I got them both the other night but got so frustrated chasing them around the zenith I only did notes on one. They look good in the same FOV though.

Glad you found the charts helpful with the SMC. There is certainly a lot to look at there.

I haven't specifically gone looking for it yet, but I must have a try.

It's quite a good site, the surrounding hills seem to keep the clouds at bay rather well.

It was quite difficult to work out which way I should tilt/turn the dob to get where I wanted and when to do the complete flip through zenith. I found chasing down 1 or 2 objects just as or more satisfying than ticking off a list of a dozen items.
