Hello, I am doing photometry of an exoplanet but the exposure time of the frames are quite short, 15 seconds. I was wondering if there is a way I can stack only a fixed number group of frames to increase the SNR, automatically because I have something like 430 frames and doing it manually is quite time consuming. I know Siril can handle scripts but my knowledge in code is not great. Thanks in advance.
Yes, it is possible. You can combine the power of Python with Siril to create such scripts. You have an example of superstack in the comet tutorial here: Siril - Working with Comets.
This is awesome, thank you!
