M64 - LRGB - reprocessed data

Revision title: Same data, latest processing steps

As I'm ramping up the steep learning curve, I revisit old images (see revision C, initial processing, to compare with).

M64 is a beautiful target, but quite faint; only 1 hr per channel captured, which is quite low.

Shot with the C8 EdgeHD, fighting againt the blue filter dispersion.

Not much fancy processing - the key is really to perform the stretch correctly. This time, PI's MS was the winner.

I'm not about the final colors here - as I'm deficient is the red spectrum, I hope there's not too much violet/purple visible.

Feedbacks are welcome.

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.
