Hello I seem to be struggling to pull any more data of planets. This was 800 iso with about 1/40 shutter speed for about 2 and a half minutes using the helios 200mm with a 2x barlow at f10 and my canon 1300d in planetary mode in backyard eos, 5x zoom. Then about 40 percent of the best frames stacked in as2 and then used wavelets in registax 5, Do I need to up the iso and make the shutter speed as fast as possible? Also pipp seems to struggle processing my saturn avi videos and gets stuck at 64 percent. Any help would be appreciated, planetary seems alot harder than galaxies etc, thanks guys
