M81, M82, and IFN from Bortle 1 @ 10K Feet

I took advantage of a windless, moonless, and cloudless night to drag my gear up to the top of Haleakala. This is one of the targets I grabbed with the remaining few hours of dark skies in the early AM (3.4 hours total integration). This was my first time to image in a bortle 1 zone but what was icing on the cake was that at 10K ft, there was very little atmosphere to compete with. The stars almost didn't flicker in the sky. It was the best night I had ever experienced seeing wise. The clear advantage being that I was able to grab so much detail with relatively little integration time.

I took advantage of those dark skies to capture the IFN for my first time. What is interesting to me is the color I am seeing in the IFN itself. It is typically grey/white in color and here I am seeing a tint of red and even some blue highlights. I tried a few color calibration methods (Auto Color script and SPCC) to make sure it is not artificial. There was some variation between them but in both cases there was the red/brown with blue highlights.

What are your thoughts on the color of the IFN in this image?

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.
