Title: Overhauled M42

Description: A friend tipped me that Adam Block had updated his Fundamentals course with new videos describing the many new processing tools available for Pixinsight. It's been awhile since I took the course, so I checked it out. He made some major additions!

Adam worked with M42 data quite a bit and had an available image download to follow along with. I used my own M42 oldish data that I had from back in November of 2020.

This data was back from my beginning days of using Pixinsight (and using a dedicated astronomy camera).

My main goal of reprocessing was to get the hang of stretching with GHS. Adam did a wonderful job at describing the use of the GHS process (the best that I have seen yet), but in the end I used a modified STF and HistogramTransformation.

There are many issues with the stars, and the coloration might be a bit “Pepto Bismol” but I just left it because I like it.

Thanks for looking and comments welcome!

Jim

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.
