M3

My image of the Globular star cluster M3, taken with my 1300D DSLR Canon camera mounted on my 80ED APO Skywatcher Refractor telescope with a field flattener. My settings were 40s and 800ISO. I captured 150 images, 30 flat frames and 30 dark frames. All were stacked in Sequator and processed in Siril and  Gimp 2.10. My telescope was mounted on my EQ5 GOTO Mount. I used an intervalometer to control  the camera and a Bahtinov mask to focus on a bright star.
