M82 Cigar Galaxy

Messier 82 (also known as NGC 3034, Cigar Galaxy) is the prototype nearby starburst galaxy about 12 million light-years away in the constellation Ursa Major. The starburst galaxy is five times more luminous than the whole Milky Way and one hundred times more luminous than our galaxy's center. The starburst activity is thought to be triggered by interaction with neighboring galaxy M81.

The image was captured with the Celestron CGE Pro mount and the venerable Meade 12"LX200 SCT, using my Atik 383L+ m CCD at F7.16 (2182mm FL). Astronomik's Ha narrow band, and Red, Green and Blue broad band filters were used. Imaging subs were taken at 1x1 bin, -10C, and 10 minutes for all.

Image information -- 2018

Ha: 77 subs (12.83 hr) on Jan 3rd, Jan 8th and Jan 12th.

Red: 16 subs (2.67 hr) on Jan 8th and Jan 12th.

Green: 15 subs (2.50 hr) on Jan 12th.

Blue: 13 subs (2.17 hr) on Jan 12th.

Processing was done with PixInsight, following (for the most part) kayronjm's tutorial of Feb. 24th. Ha filter was used for the Lum image. R, G and B were collected for the color mix. The detail and color came out nicely.

The background for the Ha came out somewhat mottled and prove troublesome to eliminate.

North is to the right (pretty sure), and this is a slight crop due to the misalignment accumulation from the different filters and times.

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.
