I shot my Luminance frames at Bin 1 and my Ha, OIII and SII frames at Bin 2. Do any of my calibration frames need to be at Bin 2 as well for calibration to work? The message I'm getting for my Ha frames (and OIII) is "Could not calibrate. 0 of 6 images calibrated." When I tried calibrating a single image I get "No applicable calibration groups were found for this image. Please run Set Calibration." I have created Master Darks for all exposure lengths and Master Flats for all filters (as well as Master Bias). This led me to wonder about incompatibility in binning. Darks apparently must be shot at Bin 1, which makes sense. My notes on Flats mention only temperature and filters (plus focus).
