NGC 2403

I was a little surprised how large NGC 2403 was in my Esprit 150 . This image is cropped but only a very little bit, so I guess it is one of the larger galaxes one can image. Im generally pleased with this rendition but I'm never totally pleased. The total imaging time was about 14.7 hours which is kind of short for me , so I can't help but wonder what a longer exposure would have looked like. Total exposing time and individual sub exposure times are things that I am uncertain about. I'm just not sure how much is enough and what is more than I need. I also wonder if a little Ha would have helped. I see some others images of NGC 2403 with Ha added and I now think that would have been beneficial. I used curves with a game script luminance mask to push out some of the red but did not want to go too far with that. I also used HDRMT (Pixinsight) to get some more detail out of the galaxy.
The exposure times by filter are:

B 68 x 180
G 74 x 180
R 72 x 180
L 80 x 180

Total 14.7 hours

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.
