Reply To: Software for photometry (image calibration)

I believe the flat-darks calibrate the flats so you get master darks and calibrated-flats.
Platesolve your stacked image and you can do photometry on the stars and also any comets. If you do the Tools – Calibrate Photometry command it also creates MZero in the fits header (which I recently checked against Astrometrica’s version and it closely agrees).
