Season End, M13 LLRGB 3 Hours
21/04/2009 (13:21) by Petri KehusmaaThis is one of my last targets for every imaging season. This year I’m imaging this great cluster with RC for the first time! Total exposure time is 3 hours (details in gallery). Seeing was pretty good but I managed to put couple of bad frames into luminance stack and therefore some of the stars look like triangle.
