NGC 6882 and NGC 6885 - Open Clusters

Spent some time bouncing around a few summer-time open clusters on the only clear night available to me last week.

Enjoy, and feel free to share your thoughts and criticism. I never want to stop learning and improving!

Acquisition and Pre-Processing:

* Best 109 (of 150 total) x30s Lights weighted using the following subframe expression:

(10*(1-(FWHM-FWHMMin)/(FWHMMax-FWHMMin))

+ 15*(1-(Eccentricity-EccentricityMin)/(EccentricityMax-EccentricityMin))

+ 25*(SNRWeight-SNRWeightMin)/(SNRWeightMax-SNRWeightMin))

+ 50

* Stacked with Linear Fit Clipping and CFA Drizzle 1x with 0.7 drop shrink

Color Calibration:

* DBE -> Background Neutralization -> Color Calibration -> Photometric Color Calibration

* Assign RGB Working space to 1,1,1

RGB Processing:

* TGV with a low contrast mask and strong edge protection

* MMT noise reduction with a high protective luminance mask

* HSV Repaired Separation Script

* Arcsinh Stretch to non-linear

Luminance Processing:

* Extract Synthetic Luminance

* Masked Stretch and Curves

Final Touches:

* LRGB Combination of L with RGB

* Chrominance noise reduction on the brighter stars to eliminate grid-like structures

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.
