I like cold. Then I can run the camera very cold, say -60C and have a really clean image. I do all my imaging from my easy chair. I rarely go out to the observatory. Everything is controlled through my lap top computer. I stay nice and cozy by the fireplace.

Yes, with three or four times the Luminosity image I could light up the dust a lot better. My scope works at f/10 which is very "slow" compared to astrograph's that work at say f/3.5. I need 8 times the exposure. But I get a much larger image scale so it all is a trade off.

It would really start to show up well at 3 hours or so rather than the half hour the sky allowed me. I'll go back and add time when I get a chance. I was really surprised how well it did turn out for so little exposure time.
