For experiment, lunar and solar Seestar S50 data were stacked and completely processed in ASIVideoStack. The lunar data are 75% of frames in a 3 minute RAW AVI and the solar data are 100% of the frames in a 37s RAW AVI captured in a rare gap in the clouds. The data are uncompressed right up until the moment that the processed JPG is saved. It should be noted that a 100% quality JPG is indistinguishable from an uncompressed image to an observer. However, JPGs are not suitable for much further processing as quality will be lost with each saving. However, if a 100% quality JPG is immediately converted to an uncompressed TIFF or PNG then limited further processing is possible. No further processing has been done here.
