M51 Whirlpool Galaxy

Revision title: GAME mask, denoise with MLT using the mask and sharpened with MLT a little bit

Last night I tried an imaging session with M51 the Whirlpool Galaxy: around 4,4 hours with my SkyWatcher 200PDS and ASI533MC camera. At 3h in the morning something went wrong with the autofocus: ASIair says "AF succeeded", but the image was completely out of focus. I assume that there is some mechanical problem with the connection of the EAF to the focuser, I have to check it before the next astrophoto session.

M51 is a very common and prominent deep sky object. "M51 is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus.[5][6][7] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy.[8] Its distance is 31 million light-years away from Earth."

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.
