I’m using a Canon EOS R6 (pixel size 5.36) and a 150mm lens set at f3.2 (Sigma 150mm 1:2.8 APO MACRO DG HSM). I’ve tried stacking in both Siril (which only worked with OSC-no-DBF and otherwise failed for some weird reason). I tried stacking in DSS, and that worked, but none of the images I’ve gotten have been able to be plate-solved.
I photographed M31. I shared the whole imaging folder, but the files I’ve tried plate solving are those in the “Fit files” folder.
