A short test image taken between clouds last night. 10 seconds sub exposure x 6 exposures each LRGB (60 seconds total exposure for each color).

Rolando,
Yep, pretty short exposures, but cool image. I like the "more color" best.

What are you testing?

Focus sure is nice and sharp. I also like the more color version best.
Cheers,

Ditto on the "more color" preference. Part of that is liking the sky not quite so black. Can you post a flat from that scope? (or have you somewhere?) Or do you even need take them with most exposures? I would guess you wouldn't need one with something like this, but with something really deep it would be interesting to see how much difference it makes.
