M51 - The Whirlpool Galaxy

I have processed this image several times. Taken from an extremely light-polluted city area with the L-Pro light pollution filter, the image showed a lot of gradient on my integration. I finally managed to do a decent job at reducing the gradient using the Light Pollution Tool in AstroPixel Processor. Then, I used NoiseXTerminator in PI (the new add-on) to de-noise it. I used 60% and it seemed more than adequate. Finished it with photometric color calibration and curve stretching. I think I could increase the saturation, but I am happy with the result. Final touch up in Adobe PS for cropping and a darker sky. It's very difficult for me to image M51 from my backyard with all the sorrounding lights and the light dome over the city, but I am happy with the results. What do you think?

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.
