M101 - unusual H(HO)O

This is a tough one for me, probably for all, but some of the images I have seen here on Astrobin are fantastic. Maybe it is the Florida light pollution that interferes with me. I gave mostly up on an RGB image of M101, but I like it so much that I tried to get some narrow band images together and well, for sure not a master piece, but at least an image that I can work on. I have some F/2 Baader Hα data still to be processed, let's see if those will help.

Red = Hα; Blue = OIII; Green = 50/50 Hα/OIII. Some color corrections were needed since the final image turned out to be too Red/greenish.

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.
