Messier 81 and 82 in Ursa Major

Link: https://stevemilne.smugmug.com/Photos/Sky/Galaxies/i-h6dHJpJ

Messier 81 (Bode’s Galaxy, NGC 3031) and Messier 82 (the Cigar Galaxy, NGC 3034) are around 12 million light years away in the constellation of Ursa Major. The irregular dwarf galaxy Holmberg IX can be seen below M81 in this image.

To the left of Messier 82, there is a small arc of nebulosity visible in the Ha data. This is galactic halo material that has been ionized by the superwind shock or intense ultraviolet radiation from the young, massive stars in the galaxy's core (Information: APOD). This ‘cap’ is around 35,000 light-years from M82.

M81 and M82 were photographed between 12 February and 21 March 2023.

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.
