Opening a FITS file

It would be nice to have the ability to work with a FITS image in Photoshop directly when doing astrophotography.  Currently, free and other software will do this such as GIMP and Affinity but not Photoshop.  I would imagine that this would be an easy addition since other software is able to do it.  Now the only way to work with is, short of installinga ten year old plugin, is to convert to a TIFF.  Please consider adding the ability to work with a FITS file.
