Hi, I want to use SIRIL to do aperture photometry on my Mac using just a single image. I find the instructions confusing. I click on the photometry button lower RHS tool bar and click on the variable, but Siril won’t let me click on comparison stars. It just resets the star as the variable. What am I doing wrong please?
Hello, if you are using only one image, I think you can only calibrate magnitude with one star, using the setmag command. The light curve operations with comparison stars are for a sequence of images.
