I have batches of lunar images captured with a Canon 60D which has a resolution of 5184 x 3456(24MPix??). I never had any trouble stacking images from my old Canon 350D (Still an excellent camera) which has a much lower resolution. Neither Autostakkert or registax work. With Autostakkert I get the error that I have run out of ram ( I have 16GB) but windows shows this is not the case. Is there a way to stack lunar images from the 60D without cropping all the images?
