Current number is due to limited battery life (max 75x 2m exposures on a charge after time taken for flats and occasional refocusing) * Brigher stars are blown out. Need to reduce exposure length next time * Quite a lot of noise in the dark region between stars. More dark frames needed? Or just more integration time? The Carina image of MAY-2020 doesn't have this issue and its got a lot more of both. Things to do differently next time: * Check histogram and image max pixel value to ensure nothing is clipping. Reduce exposure time as necessary * More dark frames
