Here's another decent image. My second so far. I'm really loving the Canon 30D. The subs were unguided and this is reflected in the final image stack. The wind didn't help either. I ended up with 9 usable frames out of the 20 I took. Okay, details:

Canon 30D (unmodified) @ ISO 800
Canon 75-300mm zoom lens @ 300mm & F/7.1
Losmandy GM-8, unguided and no PEC
Manual stack of nine 2min subs
All processing in Photoshop CS2.

Comments and suggestions please.

After researching my processing techniques, I have determined that at 300mm, f/7.1 is only 2 stops down from full aperature. I think the coma might disappear if I go to f/8. What do you all think?
