I use either a DwarfII or Dwarf3 smart telescope for my imaging, and what comes out of that is already pre-processed in a variety of ways. The telescope does its own stacking, and has a built-in link to a cloud post processor. So what I get is two images - one denoised and with basic image optimisations performed, and ano...
