Deep Gasses Around M81 M82 and NGC3077

I was intrigued after seeing images of the "cap" on M82 and wanted to take a deep look (40hrs) at the M81/M82 region in both Ha and OIII. There is a lot of structure around these galaxies and a large arc extending below NGC3077 that I have never seen before. There is also the very intriguing Ho IX 9&10 hydrogen structures just below M81.

In M82 you can see the hydrogen reaching up to the cap although I have read some controversy if that is coincidence or if it is truly part of the starburst outflow.

In the large loop extending below NGC3077 there is listed [CVL2009] Garland-3 identified as the brighter bead on the right of the loop. If anyone has more information on this structure that would be very interesting to read about! There is a ton of cataloged items in M81 to explore more fully. Will be working on uploading a detailed annotated version.

I did find a great paper on Ho IX 9&10: https://www.aanda.org/articles/aa/pdf/2005/01/aa1200.pdf

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.
