Thanks everyone!

Good work.

Hi Rick, I've read a bit about ISOs, and I'm yet to be convinced there's anything to gain from going over about ISO400-800, except for noise and lost dynamic range. Though I could do with testing this more fully, there's logic that suggests you don't register any more photons to different intensity levels above this point. So hopefully I'm not wasting time! And I'm pretty happy to reach a limiting mag of 19.9 from the suburbs! I want to try stacks of the same exposure and ISO400/800/1600/3200 to be sure, in case one study in particular on a slightly older (40D) camera is not relevant to the 60D.

Hi different Rick! Yes, not quite as smooth as I'd like, and a bit brown in the colour, can't wait to try dark skies. And you're right about the registration, which appears otherwise excellent, so I can't quite explain why the dust lane is not quite so good. Might look into it some more if I continue to get very cloudy skies
