The Bode Galaxy

Revision title: M81 INTEGRAZIONE

More experiments with the old small Asi 178 MC Cool camera, which with its small pixels, correlated to the aperture of the C11 and a very high focal ratio, brings me to a good final resolution. Too bad, the climate is not on our side, I selected the files not disturbed by the clouds, about 75% were deleted.
The Bode Galaxy, (also known as M 81 or NGC 3031) is a spiral galaxy located approximately 12 million light-years from Earth, in the northern constellation of Ursa Major. M81 is estimated to contain approximately 250 billion stars, making it slightly smaller than our Milky Way. This and the nearby irregular galaxy M82 are the most prominent members of the M81 group of galaxies, of which M81 itself is the leading member; it seems that the two galaxies met a few million years ago, causing the deformation of M82. Today the two galaxies are separated by just 200,000 light-years. Its distance is well known and has been estimated at 12 million light years, thanks to the discovery of a large number of Cepheid variables, many of which were made by the Hubble Space Telescope, and thanks to the redetermination of cosmic distances carried out by the Hipparcos satellite.

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.
