M81 & M82

M81 and M82 L(Ha+R)GB image with a total exposure of 352 minutes. 8 minute subs were captured with a ST2000XM on a WO 110 with a 0.8 reducer/flattener. Considerable processing was involved in removing gradients and noise. Mount was a CGEM which works well with the scopes. Software included CCDStack, CCDSoft, Registar and Photoshop C4. May 2010
