Did M16 in both LRGB and narrow band. I prefer the SHO version.

Description: Ok, when I originally processed this, I my attention was focused on the central area around the pillars. I didn't notice the ringing around some of the stars in the nebulosity surrounding the core. I'm uncertain how/when I introduced them, so I decided to reprocess the data. Right after the initial combine, I removed the stars, so subsequent processing of the nebula wouldn't affect them. Since I also shot this in RGB at the same time, I decided to extract the stars from my RGB data and use those instead. This also exposed some tiny stars that didn't show up in the original SHO version. For some reason, the structure was a bit more defined in the original and I can't figure out how to get back there, but the star ringing is a bigger sin, so this is the version I'm going with.

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.
