M17 The Omega, or the Swan nebula. I used a 1300D DLSR Canon camera. Settings were 1 min at 3200 ISO. The camera was mounted on an 80ED APO Skywatcher refractor telescope with a field flattener and a 2 inch Optolong L-eNhance filter. The telescope was mounted on an EQ5 GOTO Mount. I used a Bahtinov mask for focusing on a bright star, and an intervalomerter to control the camera. The image is a stack of 140 images, 20 flat frames and 25 dark frames, stacked in DSS and processed in Gimp 2.10 and Free Photo Noise. The image was taken down in Pitton cross campsite on the Gower peninsula under Bortle three skies.
