New subscriber to PS CC here. I take multiple exposures of the night sky and stack them in software to make dim, Deep Sky Objects (DSOs) like nebulae and galaxies visible. This method is very popular among astrophotographers. The format of choice both for acquisition and stacking appears to be FITS files. I was surprised to find I can't open FITS in PS. I have to convert my FITS files into something PS opens natively. I know of 2 old standalone freeware packages which can open and convert FITS but I wondered if anyone knew of a way to do it from within PS. If not is there any chance that this function could be added in the future. Most, if not all, astroimagers use PS in their workflow so I would have thought there would be demand.
