Gain/Offset METAdata in FITS headers ?

[kirkster501]

Hi guys, any idea how I get this metadata please?  When looking back at CMOS subs I want to know what G and O I used but these parameters do not seem to be written to the FITS header.  I think I am probably missing something.....

I think it's in part down to the capture software:  my version of APT writes the gain into the header, but not the offset,  while ASI Image writes the header in a different order but does include both Gain and Offset.

Afraid I don't know enough about Sequence Generator Pro (assuming that's what you use?) to say if this can be edited ?
