About this image

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).
