The title says it all. I am working with two Canon DSLRs on a Tak FSQ106 riding on a CGX-L. With all equipment working perfectly, over the last couple of nights I acquired 139 3-minute subs on my chosen target, plus darks, flats, and bias frames. DSS will load all darks, all flats, and all (141) bias frames, but it stubornly refuses to load more than 116 "light" frames, leaving 23 light frames out of the stacking process. I have both an older (3.3.2) and a newer (4.1.1) DSS version, the same happens on both.
Any ideas on how to persuade DSS to load more light frames? And any suggestions on the best way to get the most of my data without losing 23 frames?
