M34 Open Cluster Comparison of Star Deconvolution Methods from BlurXTerminator and GHS

Revision title: Crop of Original with 25% reduction of halos in BlurXterminator deconvolution and GHS stretches.

Been a lot written on BlurXterminator recently and I especially like Adam Block's video.

There he describes how open clusters are a nice way to determine how well your deconvolution is working. I had this data left over from of technical work on my camera using M34 as a target, so applied the system. I also am under the influence of the GHS Guys and have used their sequence of stretches to bring out the colors in the stars.

The workflow is:

ColorCalibration
BlurXterminator
GHS S1 Hyperbolic
GHS S2 Linear Clip Blacks
GHS S3 Hyperbolic Color
NoiseXterminatory
GHS S4 Linear Clip Blacks
GHS S5 Saturation

The image on the left below is the original with No_BlurX; the middle has default BlurX setting, and the one on the right has a 25% halo reduction applied.

All the GHS stretchs are the same.

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.
