M82 (1-9-2021)-1j.jpg

 

M82 is a close neighbor to the nearby spiral galaxy M81 which is located about ½ degree to the south. These two form an interacting pair and M82 bears the scars of a close encounter with M82 about 100 million years ago. The dark dust lanes that cut across the central region of the galaxy are very distinctive and are easily visible in modest telescopes. M82 was originally classified as an irregular galaxy, but detailed studies had shown that it is actually a spiral seen nearly edge-on.

Looks good to me, also very good detail captured near the core.
