M17 in 56 minutes.
Experimenting with a scope on loan. Looks promising.
It's been a while since I imaged M17.
Meade LX90 ACF F10 8" SCT, Canon 1100Dfs, Baader UV/IR cut filter, 112 x 30 seconds unguided. Yes I know. In my excitement to try it I didn't bother with guiding. Not bad for 2000mm unguided eh? Noisy, but looks good for a test. More time to fix noise. And guiding.
From Wiki "M17 The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter... It is considered one of the brightest and most massive star-forming regions of our galaxy."
