DeepSkyStacker |
Name: NGC3521 This image is the combination of two imaging sessions. The first on 27/03/2009 at Golden Grove and the second in my backyard at Greenwood on the 11/05/2010. See link for DeepSkyStacker Full details. Still needs more lights, however the extra lights frames so far has resulted in an improvement of the original two images with less processing required.
