In this two-part tutorial by Alexander Curry, he discusses the use of plate solving to calculate the field of view and target location based on the geometrical relationship between the stars within the image. Following this, Alex demonstrates how to use photometric color calibration (PCC) to correct the color balance of your image using the results from plate solving.
Part 1 of this tutorial covers the introduction to plate solving and configuring Siril with the star catalog files required for plate solving and PCC.
Part 2 discusses setting up plate solving necessary for running PCC. This section also explores various methods for determining the astrometric solution for your image, should you be solving "blind."
