IFN around M81 & M82 (Animation)

I tried a new processing with my recent dataset. First, I used superpixels in DSS to get the most out of the 40 minutes. Then, I prepared two single images: One luminance version, stretched to the limit in Fitswork and one RGB version, only slightly stretched in Fitswork (no IFN visible).

Then I put both versions into PS and removed the stars in the luminance version to get an image with only galaxies and IFN. This layer was blended into the RGB one.

This animation shows the first RGB version without IFN and the final result with some color adjustments.

NOTE: I know that I need a lot more exposure and the images have lots of artifacts. Definitely my plan for the next clear night! This is just a feasibility study!

Oh, and thanks to Marcus Wögerer for the idea!

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.
