Convert each frame from a .ser file into individual .fits files.
To use this script, you'll need these dependencies: python 3.8, pySER-Reader (here: https://github.com/Copper280z/pySER-Reader/tree/master), numpy, astropy,
Using the script is simple: type into your terminal:
$ python ser_to_fits_converter.py (your .ser files)
My method has been moving all of the .ser files that I want to convert into .fits files into the same folder, and using *.ser in place of "(your .ser files)". Feel free to post issues and I will get to them when I can.
