I am having difficulty calibrating images obtained using AAP. The fits header incorrectly has a value for focal length that is 1/4 the true focal length. This occurs in the Light files. the Dark and Flat files are correctly recording the true focal length. I am using ASI6200 for capture, but this has also occurred using a Canon 6DMII . Why does this occur? Is there a user solution. AAP firmware updated on 19 JUL 2021.
Doing a little research on the PI Forum I came across a reference to this problem and an articulate description of the problem. I copy the reference here: "The astrometric solutions in the FITS headers of these files captured using the ASiair Astrophotography Controller do not match the images in the files. In particular, the image size is different. These errors cause incompatibility with other software that processes FITS header data correctly. This incompatibility is made worse by the use of non-standard keywords, such as 'IMAGEW' and 'IMAGEH' instead of the standard 'NAXIS1', 'NAXIS2'. All FITS header content should comply with the FITS standard, available at http://fits.gsfc.nasa.gov/iaufwg/."
I would appreciate a response from ZWO. I am unable to calibrate images from the ASIAIR PRO using Pixinsight.
