M78 & Barnard's Loop

This image has proved to be the most difficult for me to process by far. I found out the hard way that my Astrodon filters were the cause of the bloated stars in my luminance files to the point that they were unusable. The blue showed some bloat but was salvageable. I have since gotten an IR-cut filter that helps with the Lum but by that point, this region was out of good visibility for me. So, to overcome it, I created a pseudo luminance with the RGB files and then enhanced that further by using the Max(x,y) function in PI's Pixel Math and combined it with my H-alpha data. That allowed me to get good luminance data on both M78 and the loop in one luminance file. And for my RGB file, I merged the H-a data with the red channel. The final result could be classed as a HaRGB-PseudoLUM-HaRGB image.

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.
