IFN south of rho UMa in Ursa Major

I continue my hunt for Integrated Flux Nebulosity (IFN) with the RASA. The big yellow star to the left in the image is rho UMa and south is to the right in the image (turned it that way for better framing). The big yellow and blue stars in the lower left quadrant are sig01 UMa and Sig02 UMa, respectively. My obsy is in a rural area and SQM this night showed 21.4, so quite dark. That helps a lot when hunting for IFN. The 8" F/2 scope also helps. That combination allows for detecting quite a lot of colour in the IFN.

I have not seen any images of IFN this area this close up, but there are some wider field images by Nawratil and others that I use to orient myself in my hunt.

Version A shows an annotated image (done in PI) revealing a lot of small galaxies from the PGC catalogue.

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.
