I've wanted to capture M78 for a long time. Last year I tried, but didn't get enough time on it. So I braved sub-freezing temperatures and crazy humidity the last few nights to get this LRGB image. It didn't get high enough until 2AM, so it's still not as much time as I'd like. Usually when time is short I skip "L" and just do RGB, but I had to capture some data while it was really low, which meant those frames weren't very sharp. So I captured L last - when it was at its highest (before sunrise) and used that to provide the sharpness.

Thanks, Trevor. It's a little less than 4 hours: RGB = 6 x 8 minutes, L = 16 x 4 minutes. Between 2 and 4:30AM over 2 nights.

Well worth the effort...what was the total time?
