The dynamic range of this target made for some tricky processing. I like how things look now, but I might come back to this with fresh eyes later. I tried to incorporate some new steps in my Pixinsight workflow - Bill Blanshan's color mask and narrowband normalization equations were key contributors here.

Title: Re-processed

Description: I took another round at this as I feel like I went a bit overboard with the colors on rev1. I only cropped the edges to show the wider field, and I tried to emphasize some of the finer structures in the nebula's core (thanks BXT). I processed this as a normal RGB image without any attempt to go at the channels separately. Which do you prefer?

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.
