In this field we have three prominent galaxies, M81 - Bode's Galaxy, M82 - the "Cigar Galaxy," and NGC 3077, an elliptical galaxy.

In addition, there are about 70 smaller (in arc-degree size anyway!) galaxies with PGC identifiers, as shown in the annotated version (done with PixInsight).

The data for this image was acquired over 15 nights from January to May 2020, with a Skywatcher Esprit 80 refractor and an ASI1600MM cooled camera.
Ha and RGB filters were used. L data was also acquired but it didn't add anything to the image so I left it out in processing.

Thanks for having a look!

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.
