Description

While M81 and M82 are great broadband targets, they are also rich in hydrogen-alpha gas, especially the starburst galaxy M82.The use of a camera modified to be more sensitive to the H-alpha spectrum helps bring out these hydrogen-alpha regions.Shot using a Nikon Z6 (Hydrogen-alpha modified mirrorless camera);A Sky Watcher Black Diamond 80ED doublet refractor with a 0.8x reducer/field flattener (FL of 480mm); with the FL extended to 960mm through the use of a Nikon AF-S TC-20E III (2x Tele-converter). Even at 960mm, the objects are quite small; so the image is heavily cropped.

Shot At ISO 3200.
