I am having trouble displaying RGB FITS files that were captured by my Nikon, using INDI from the Python cli.
Sample code that I have found out on the interwebs don't work very well with 'real' RGB FITS files.
Opening the file and reading the header yields:
Filename: ./M_57_Light_001.fits
No. Name Ver Type Cards Dimensions Format
0 PRIMARY 1 PrimaryHDU 52 (6016, 4016, 3) uint8
The first problem that I hacked my way through was the need to 'reshape' the image data after opening it.
