Revision title: Bode's & Cigar Galaxies - M81 / M82 - Revisited

A beautiful pair of galaxies in the constellation of Ursa Major discovered by J.E. Bode in 1744, recorded as "(M 81) a nebulous patch, more or less round, with a dense nucleus in the middle" - "(M 82) a nebulous patch, very pale, elongated".
M 81, the larger of the two, is positioned about 10° NW from Alpha Ursa Major and is separated by 38" from M 82. The two are forming a nucleus of a small group that might be the nearest group of galaxies outside our own local group. Published distances range from 6 1/2 to 9 milling light years away from us. The M81 group possibly contains about a dozen members. [R. Burnham Jr. - Celestial Handbook Vol.3]

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.
