I think  I am happy with this one.

Neil,

That is a cracking image, what kit did you use for that, exposure info would be interesting to see as well!

28 two-minute subs at ISO800 using th3 Canon 450D with th3 150PL. I was amazed at how well it picked out the fainter bits for so few subs.

I'm trying another run combining with 100+ 30 second ISO1600 subs from last year.

If it works OK I will try drizzling a crop.

Looks good. 2 minutes subs on an EQ3 with a long fl, and still nice round stars, that's quite a feat.

If I were you, I probably wouldn't mix in shorter subs. You run the risk of revealing the fixed noise pattern of the camera (despite bias frames). But if you can manage 50+ 2 minute exposures, that would really bring the noise down. Otoh, 100 minutes clear sky may be too much to ask for.

Thanks for sharing
