Stephan's Quintet
Observing location
Kelling Heath campsite
Celestron 8SE, OAG, 0.77 flat/reducer
Atik 460EX mono, SX guide cam
Skywatcher AZ-EQ6-GT
Baader luminance filter
Lum bin 1x1, 10 subs of 7min each

Taken at Kelling Heath Sky Camp, so good dark sky.

Sky cleared about 1:30 and I had hoped for a full LRGB set. However, I misjudged the altitude of the trees and, after obtaining a series of Red subs, the Green were spoiled! Nevertheless, the Luminance files alone (used here) give the essential details of one of the showcase examples from the Hickson catalogue (#92).
