Anastasiia, if you want to determine the magnitude of an star or another astrophysical object, you must to learn something about photometry in advance. Then you may use for instance IRAF (Image Reduction and Analysis Facility), a proffesional tool for aperture photometry. There is sufficient information on the web.

Dear Anastasiia Nahurna,

If the question is about software that performs this task I think that machine learning, python, would be some of those that can give a direction in this sense. I'm currently developing a project on the importance of meteorites in my region at a more elementary level for primary school students.

Best wishes,

Fabiano
