Revision title: NGC 4565 REVIEW C

This is the final version of my NGC 4565.
I used an hdr mask that protected the whole galaxy except the 2 bright halos of the galactic center. In this way the outer arms in front of the galactic nucleus have remained unaffected by the HDR tool.

As a final process I created a luminance mask and applied the unsharp mask tool very softly to highlight the galaxy dust

The details, even though it's only a 140mm, are impressive.

This is 8 Hours in LRGB.
I also shot 20 hours in halpha but the contribution in the red channel is irrelevant, so I decided to avoid merging it

At the bottom left you can see IC 3543 and IC 3546.

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.
