A well-known pair of superb galaxies M81 and M82 in the constellation Ursa Major.M81 is the beautiful spiral galaxy almost comparable in size to ours and located 12 million light-years away. M82 is apparently an irregular galaxy, but it hides within it two spiral arms. In the center of M82, there are lot of bursts of activity with a fairly high star formation rate. The photo was imaged from the remotely piloted observatory in Portugal by the AstroDarkTeam composed of Stéphane Rolland and Pascal Gouraud.This image is the result of the assembly of exposures on the 5 LHaRGB layers, which represents a total of 32 hours 30 minutes over approximately 14 nights, including 13 hours and 15 minutes in Luminance, 11 hours 16 minutes in Halpha and 8 hours in RGB.Thanks again to the French Astro ARO team for the efficient and effective management of this superb site that hosts us.

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.
