fitz

fitz is a command-line utility for batch operations on FITS files (astronomy images).

It started as a tool to compress and decompress FITS files, but has grown to support debayering raw FITS images, auto-stretching, and splitting OSC images into separate red, green, and blue FITS files for narrowband processing.

fitz can also preview FITS images right in the terminal.
