IC5146 WIP - Staunton River Star Party - Test of ArcSinH

Experiment using MaskedStretch for L and ArcSinH to stretch RGB. Then combine with LRGBCombination.

You end up with some color - lots of color. It preserved the color all right - WAY too much color. Stars ended up with strong halos. I cleaned it up with some masked HueSaturation in PS but in the end I think it is too much for my tastes. I prefer a more reserved "natural" look.

I don't think ArcSinH was the problem. I just need to be more refined in my use of the tools. I also need to understand why the combined RGB frames have asymmetric halos. Probably something to do with some of the color obtained on one side of the meridian and some on the other.

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.
