Not sure why, but I’m making a final image from 85 lights, 150 darks and 40 flats. I created the master flat this morning and went to work while the rest was going to be processed. I set my computer to never go to sleep, just the monitor so that shouldn’t matter, it was still busy registering lights when I got back home at the end of the day. I did use LNC with 1 iteration, but still that seems very long as if it paused or so.
