The Fair, The Bad, and The Ugly
I was pleased with the results of M45, 20 frames at 3 minutes each, ISO 800 at 55mm, f/5.6, the sky background came out reasonably clean, there is decent nebulosity, and the framing was about right. I had an enlargement made of this one and it looks good.
My M42 was imaged with 20 frames at 3 minutes each, ISO 800 at 55mm, f/5.6 as well, but I am displeased with the background on this one. I've tried processing it a couple of times, but I think the problems lies in my dark frames.
M31 is a nice target, but this photo does no justice to it. Shot 20 frames at 3 minutes each, ISO 800 at 55mm, f/5.6 and using the same dark frames as used with M42 above, this was very well placed in the sky, the night was perfectly clear with excellent seeing so I can't blame it on anything like that.
