M31 the Andromeda galaxy

M31 the Andromeda galaxy taken with a Canon 1300D DSLR camera with a Rokinon 135mm prime lens at f/2.8. The camera was mounted on a Star Adventure 2i pro tracking mount. Settings were 50s exposure and 1600 ISO. I captured 50 images, 25 dark frames, 25 flat frames and 35 dark-flat frames. All were stacked in DSS and processed in GraXpert, StarNet++ and finished in Gimp 2.10.  An intervalometer was used to control the camera and a Bahtinov mask to focus on a bright star.
