IFN around M81/M82

M81 and M82 and surrounding area, imaged with a Rokinon 135mm f/2 at f/2.8. 97 180-second light frames with my Ha-modded Canon 600D and an additional 165 light frames with my stock 500D. Each camera had 30 darks, flats, and dark flats. Tracked with my Skyguider Pro camera tracker.

The highlights are a bit blown out because I wanted to show the background dust, but I blended in a low-stretched image to try to show some details in the galaxies. Processed in Astro Pixel Processor and GIMP. I used Starnet++ to remove the stars from a highly stretched version to show more dust, and blended this back into the image as a layer to try to bring out more detail.

C&C welcome!

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.
