M41 surrounded by IFN

This is an attempt to picture the IFN that surrounds the open cluster Messier 41 which is not normally seen in pictures, but it clearly shows on Surveys.
I employed double telescope parallel setup, shooting L with Esprit 100ed reduced by Apex 0.65x-L reducer to 367mm F3.6 and the very sensitive QHY268mono camera on Extenden Well picturing mode dooing long (for an L) 300" lights, while second telescope - Takahashi FS60 reduced to 255mm F4 by dedicated 0.72 reducer equiped with modified Nikon D750a camera shoting OSC color.
More time would've benefit the image but even with a few hours the IFN is clearly visible.

Technical details:
Telescope 1:
Esprit 100ed + reducer Apex 0.65-L = 367mm F3.6
Qhy268m @ Extended Well mode, Gain 0, Offset 20
StarlightXpress FW + Antlia filter L = 35 x 300"
Guiding with QhyMiniScope and Qhy5l-ii-m
Orion Sirius EQ-G mount (Rowan belt mod)

Telescope 2:
Takahashi Fs60 + 0.72x reducer = 255mm F4
Nikon D750a @ iso200, 34 x 300"

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.
