MichiP Posted August 6, 2013 Report Share Posted August 6, 2013 Hi Dave, wow, great image!!! Thank you for sharing all the detailed information about the imaging process. Regards, Mike Link to comment Share on other sites More sharing options...
mattssporre Posted August 10, 2013 Report Share Posted August 10, 2013 Super image Dave! I see that you binned the RGB images 1x1 as well as the L. "Normally" - not sure what is normal though - you bin L at 1x1 and RGB 2x2 OR use only RGB binned 1x1. Any particular reason for this way of combining?

DaveK Posted August 12, 2013 Author Report Share Posted August 12, 2013 Thanks for the kind comments. This is one of my best images. I try hard but I am still quite new at this astrophotography hobby. I have been experiementing with binning the traditional L 1x1 and RGB 2x2 in comparison with all image binned 1x1. The images LRGB binned 1x1 appear better to my eye. Perhaps its an illusion? Link to comment Share on other sites More sharing options...
