The Black Eye Galaxy (M64) - RGB only

My last image for a while on the AT130 EDT before teardown to move over to the EdgeHD 11 now that the CEM70 is working so well. Just need a little more reach for these galaxies, even though summer is approaching...

RGB only. I captured some Ha during moonlight as an experiment, but not useful on this target in practice. So this is basically 2hrs each on RGB at unity gain on the ASI294MM, and cropped.

Continuing to refine my process a little:

Channel Combination (no Linear Fit now)
BXT correct only
Gradient Correction
BXT gently
NXT gently
EZ Soft Stretch (it just works for me)
SXT to work on galaxy only (stars just needed gentle saturation)
Local Histogram Equalization gently (L-masked to galaxy only)
Unsharp Mask gently
NXT repeat
Rescreen stars
Bill Blanshan's SCNR v6
EZ HDR
Final adjustments to galaxy core
Final crop in Lightroom and a little more sharpening

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.
