Description

M81 and M82, a lovely interacting pair.

M82 is the sigar-like galaxy in the image and is 12 million lightyears away. It's a place of intense star formation, very likely caused by the influence of M81 close by. M81 harbors a black hole in its center of none-less than 70 MILLION solar masses (so 70 million suns fit into it).

I love to see the amount of signal coming out of the background, I want to add more data and especially an H-Alpha session still.

This is an HDR combination of 80x 30 seconds and 85x 180 seconds. Calibrated in APP and processed in PixInsight. edit: The final version has an extra 11x 15 min of H-Alpha data added.
