NGC 2903 - LRGB

I wasn’t sure what to expect with this target as it’s a pretty small galaxy for my equipment.
This was about 30 minutes of each RGB toward the end of the night but before sunrise.
Overall, I’m happy with the colors in this one but, I have some vignetting in the corners.

Processing in PixInsight

WBPP for stacking, registration, local normalization, and integration. The RGB channels were combined
with channel combination and then run through ABE prior to color correction with SPCC. Linear noise
reduction was applied followed by SCNR to remove excess green. BlurXterminator was run to help
sharpen the stars prior to stretching with STF and HT. The luminance was blended in with LRGB combination.
An inverted star mask was used while curves boosted the star’s color saturation. The mask was then used to
protect the stars while contrast adjustments were made on the background and a final noise reduction applied.

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.
