Hello,
Been using a Baader modified Canon Xsi, and noticed when stacking that the ISO is not being written in the FITS header. This is making it more of a pain to automatically align my darks taken at different iso’s.
I looked and don’t see a setting for this - it happened automatically on my Nikon D5100.
Mike,
I can’t duplicate this with my 60D. Any info you can provide to assist would be helpful. If you can upload an unaltered FIT somewhere I can take a look as well as the SGP log that created it.
