The magnitude of a star can be calculated based on known magnitudes of stars in the same image. To do that, follow these directions:

Hello!
I have taken images of Standard Stars and I'm trying to calculate the extinction coefficient for each night. I've been told that in order to do that I need to measure the magnitude of the star and then draw a straight line on the plot airmass - magnitude. Is
there a way to measure the magnitude of a star using AstroImageJ?
Thank you very much!
