Omega widefield

Last night was the first night for nearly a month that it was worthwhile getting a scope out, so I thought I'd make the most of it. Seeing as the weathers been really iffy I only used my refractor so if need be I could quickly pick it up and dash for cover.

After spending about 3/4 of an hour getting a semi-decent alignment. (bit out of practice ) I rattled of a couple of avies of jupiter (see http://www.iceinspace.com.au/forum/s...&threadid=1615 ). But the main reason I wanted to get a decent alignment was I've been really envious of some of the great widefield and primefocus shots being post here lately. Excellent stuff actually.

So I thought a wide field shot of the Omega Centauri area would be great to start with. Well as the gods would have it, that was all I would get. 2 x 2 min @ISO800, FL 90mm f/5.6 at medium normal setting (forgot to check that and make it fine setting ) on the 300D. Focused using DSLR Focus. Two images dark subtracted in PS and stacked in Reg 3 no waveletting or other adjustments.

If you look really carefully you may be able to see a very faint NGC5643 (its fairly obvious in the full size) towards the lower left of the image, roughly in line with Omega Cent.
