Wide field Rosette Nebula

My image of the Rosette Nebula taken with my Rokionon 135mm prime lens and my 1300d DSLR Canon camera. The camera was mounted  on my Star Adenvter 2i pro tracking mount. Settings were 45s exposure and 400ISO. I captured 230 images, 40 dark frames and 30 flat frames all stacked in DSS and processed in Siril. I used Star net ++ and finished of in Gimp 2.10. I used an intervalometer to control the camera and a Bahtinov mask to focus on a bright star.
