M82 Cigar Galaxy #4

This galaxy has an incredible outflow of gas from its core -- an active starburst region caused by its gravitational interactions with nearby M81. It's best seen in hydrogen-alpha light. I wanted to see how the Antlia Triband RGB Ultra would do on this region, since it does a good job of passing red -- and while it's not as much as a pure H-alpha filter would get, it's a good bit and I'm quite pleased!

M82 is located about 12 million lightyears away behind the constellation Ursa Major, off the end of the cup of the Big Dipper. We are seeing it edge-on, and it's quite a fascinating galaxy with all kinds of disruption going on from gravitational interactions with M81. At 40,800 lightyears across -- less than half of our own galaxy -- it's five times more luminous, and the central core is one hundred times more luminous!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
