I processed this set of subframes multiple times, until I got something I think it's not plagued by noise artifacts. My workflow for this image was calibration and stacking in Astropixel Processor. Then took the image to Pixinsight for Dynamic Cropping (just a bit), Dynamic Background Extraction, Photometric Color Calibration (Photon Equalization), ArcsinhStretch, and Curves Transformation - just the curve for additional details of the "nebulosities". Used Adobe PS for cropping and saving this Jpg image. Decided not to do denoise using Topaz. I find that with my images, Denoise tends to "clump the noise together" and the background looks ugly. For me this final image shows some nebulosity, and the noise level is acceptable. Maybe I am just imagining stuff. But I was trying to go for as clean and natural look as I could get. And this is from the heart of a major cosmpolitan area. You tell me wha 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.
