Intro to photometry
I'm working on a project for my masters program but I'm really struggling to know if I have the right objects. The goal is to track 1 Cepheid and 1 RR Lyrae and create a light curve over the course of 1-2 weeks. I'm taking photos with my DSLR and then processing in astroimageJ. My Cepheid is RT Aurigae. I haven't decided on RR leo or U Comae Berenices for my RR Lyrae.
My main issue right now is confirming that the images I took actually contain the stars I'm looking for. Below I'll attach some images and the AAVSO chart. If someone could confirm if I have the right objects and teach me the best methods I would really appreciate it thanks!
Incase it helps I'm using a Celestron 8se, Nikon D3300, and focal reducer.
I was about to post this in r/AskAstrophotography, but I think this would be against the rules.
