This question comes in the "DSLR for Dummies" category...
I have a Nikon D5300 that I'm planning to use for the eclipse. I took some test images of the full moon last night and captured in both RAW/NEF and FIT.
When I open both files in Pixinsight, PI seems to automatically debayer the NEF file and it looks "right" in terms of color. When I try to debayer the FIT file in PI no matter what bayer pattern I use it always comes out with a strong color cast (green, magenta, blue...).
What am I doing wrong with the FIT file?
