Why do my FITS files appear in black and white?
The FITS files come from a color sensor containing the information organized as a Bayer pattern. To convert them to a colored image, it is necessary to go through a phase called demosaicing (sometimes called Debayering).
A single FITS file is not enough to generate a final picture, FITS files need to be aligned and stacked between each other. The manual of your favorite astrophotography software will guide you through these steps.
STELLINA’s innovation lies in the automation of all the necessary steps needed to generate a JPEG file, these operations can take a few hours if done manually.
