I’m a novice astrophotographer planning to capture a star trail photo. I’ll be using a crop sensor camera and shooting 15s frames at f/2 with a 50mm lens for 2 hours. That should give me roughly 480 frames. My plan right now is to capture all those frames in RAW and use Siril to stack them. I’m estimating this to be around 34GB of data. I looked around and saw that Siril doesn’t have a gap filling mode, is there a way I can use GIMP for gap filling? I’d appreciate any suggestions to improve this workflow and whether using RAWs is even worth it in this case given then amount of data I’ll have to deal with.
