The Bode’s Galaxy (Messier 81 or M81 or NGC3031) is the largest member in its group, which contains 34 galaxies, and it is one of the nearest groups to the Milky Way and the Local Group.
It is visible in the constellation Ursa Major about 12 million light-years away from us.
M81 is a grand-design spiral galaxy (having tightly wound spiral arms); it’s about 96.000 light-years diameter wide, like the Milky Way.
Bode’s Galaxy is gravitationally related to M82 (Cigar Galaxy – about 37.500 l.y. wide) and the smaller elliptical galaxy NGC 3077. Probably M81 and M82 collided with each other about 250 million years ago.
Unfortunately, there have been some foggy nights, and a relevant part of my shoots (about 4 hours) was unusable in the picture development.

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.
