The FITS header is INCORRECT on 3 out of 4 values for my main camera & scope
PIXSIZE1 = 2.400000E+00 / Pixel Size 1 (microns) <= this is correct
FOCALLEN = 3.00E+02 / Focal Length (mm) <= should be 1260mm
APTDIA = 3.00E+01 / Telescope diameter (mm) <= should be 200mm
SCALE = 1.650400E+00 / arcsecs per pixel <= should be approx 0.4 arcsec per pix
Attached is a screenshot of the Ekos telescope panel showing the correct scope values (focal length and aperture), and the Ekos debug log.
