My wide field image of the M52 star cluster region in Cassiopeia taken with my 1300D DSLR Canon camera, my Rokinon 135mm prime lens at f/2. The camera mounted on my star Adventure 2i pro tracking mount. Settings were 45s exposuresand 800 ISO. I captured 100 images, 25 flat frames, 25 dark frames and 30 flat-dark frames. All were Stacked in ASTAP and processed in GraXpert, Siril and Star Net ++ and finished off in Gimp 2.10. I used an intervalometer to control the camera, and a Bahtinov mask to focus on a bright star.
