Wide field image of M35 star cluster in Gemini taken with my Rokinon 135mm prime lens at f/2.8 mounted on my DSLR Canon camera. The camera was mounted on a Star Adventure 2i pro tracking mount. My settings were 45s exposures ISO 800, 200 images, 50 flat frames and 30 dark frames, all stacked in DSS and processed in Siril and Gimp 2.10. I used an intervalometer to control the camera and a Bahtinov mask to focus on a bright star.
