Description

Stack of 6 30sec exposures, ISO 6400. I welcome any and all critiques and advice! This is from my first night of deep sky imaging, no guiding, dark frames subtracted and stacked in Keith's Image Stacker, minimal post processing in Apple Preview and iPhoto. The sky is pretty light polluted in this direction from my place, surprised I got this!

Shot these at my Canon T2i's highest resolution, over 5100 pixel wide. Keith's Image Stacker won't handle anything over 4091 wide, and kept crashing when I tried to crop. I finally just resampled to a lower resolution. If anyone has any advice on a better path next time, please share.
