The cosmic Sigar M82

The Cigar Galaxy, Messier 82 (M82), also known as NGC 3034, or M82, is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. It is the second-largest galaxy within the M81 Group, with a diameter of about 40,800 light-years. The galaxy is remarkably five times more luminous than the Milky Way, with its central region being about a hundred times more luminous. The intense starburst activity in M82 is thought to have been triggered by interaction with its neighboring galaxy, M81. This type of activity makes M82 a prototypical example of a starburst galaxy. The starburst core of M82 is a highly energetic and dense environment. Hubble Space Telescope observations have revealed numerous young massive clusters in this region, with an average mass around 200,000 solar masses. Star formation in the galaxy's center occurs at a rate ten times faster than in the entire Milky Way Galaxy. The active starburst region, the galaxy's central starburst, and the star formation in its disk all contribute to M82's designation as a starburst galaxy.

This image marks my inaugural astrophotography attempt in Nerpio and is the first capture using my C11HD telescope. It's a composite of RGB data with an overlay of Ha data.Encountered some challenges with the flats, but it's all part of the learning curve.Clear skies and enjoy,

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.
