NGC 2903 - three processing revisions

NGC 2903 is a bright galaxy in Leo that shines at an overall magnitude of 8.9 and spans 12.6'. It is one of the brighter galaxies that Charles Messier might have included in his list, but did not. This image was acquired with some luminance data from a green/yellow zone on a really fine night with excellent seeing, with RGB data from a gray zone on a night of average seeing. The image was composed in LRGB mode, with the luminance channel being composed of both natural and synthetic luminance.

The second revision has a little less blue in the outer arms of the galaxy.

The third revision simply has the color saturation turned down. It was the overwhelming favorite when I posted a comparison with the second revision on Cloudy Nights.

Description: Better software and processing techniques warranted a fourth revision of this image from five years ago. Star size, star colors, and details/noise reduction have all been improved.

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.
