Image taken using my Rokinon 135MM Prime lens at f/2. The lens was mounted on my 1300D DSLR Canon camera, the camera was mounted on my star adventure 2i pro tracking mount. Settings were 45s and 800ISO. I took 120 images, 30 flat frames and 20 dark frames. All were stacked in Sequator, edited in Siril and finished off in gimp 2.10 using star removal and replacement, and Photopea for noise reduction. I used an intervalometer to control the camera and a Bahtinov mask to focus on a bright star. The image was taken under Bortle 3 skies in Gower.
