NGC 2403; How did Chuck miss this one?

I've been shooting some of the Messier galaxies I missed last year, but they don't rise above the trees to my East until about 11:00. To pass the time and get the scope and guidance "warmed up" I've been shooting the brightest galaxy that Charles Messier missed, NGC2403. I start imaging as soon as the SQM gets to 19 and keep shooting until my Messier galaxy target of the night rises. I then shoot each of these galaxies for 1 night only, just to be sure I get some data on each of them this season. I plan to go back to some of these galaxies if I have time late in the season.

For now I've come to the conclusion that NGC2403 is done, after 8.7h of good frames.

To get those nice red H-alpha regions and golden colored lanes in the core I used the following pallet.

Red channel= Red + ( 2xHa) -created with Pixel math

Green channel= Red

Blue Channel = Blue

Frames Used

L=34x240

R=29*240

G= 14x240 not used (more noise than Red and similar appearance)

B=28*240

H=39x240 bin 2X2 then drizzled to match

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.
