The region around M81/M82 was the first place I saw images with IFN when I started out imaging and have attempted shooting it ever since. Each year I have tried to image IFN and from Austin, it has been all but impossible. However, with my wide field scope at my dark sky observatory, this was hight on the list.

I originally started with a 4 panel mosaic to get a very large region and then realized, inspite of dark skies, the broadband mosaics are very tough given the various sky conditions and with these huge subs, I simply cannot complete it properly. This one is a 2 panel mosaic to collect some interesting structures.

I also used 15 minute subs through out to get the extra depth. The color data was challenging.. with different gradients between the two panel. Luckily it was minor enough to control. I debated adding high res detail on the nebula from Edge11 to show the Ha filaments. But I think I like as is.

The result is a a very dusty field!

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.
