Hello,
I believe I've finally figured out why FITS files produced with APT usually fail "Image Solver" in PixInsight.
A little background -- I have an iOptron CEM-120 mount and as far as I can tell it needs epoch JNOW, so I have that checked in APT (and programs like Stellarium.)
The coordinates that are stored in the FITS header are for epoch JNOW. But when using WBPP (or Image Solver directly) in PixInsight, it appears it is expecting epoch J2000 coordinates. So it usually fails the initial attempt. But if I do a search in Image Solver and it gets the data for the object (from VizieR) the coordinates are now J2000 and the image solves correctly.
So since I cannot change the epoch in APT to be J2000 (because of the mount's needs), is there some additional FITS keyword (like EQUINOX) that needs to be present in the FITS header so Image Solver knows the coordinates are JNOW?
Or is there a setting in Image Solver (also working in WBPP) that will tell it that the coordinates are JNOW?
I've asked this question on the APT forum too in case it's something they can/need to correct.
Thanks for any help,
Lamar
