Messier 16 in SHO

First proper narrowband capture with a new camera, and I probably didn't make it easy for myself. Where i'm at, M16 doesn't rise above just shy of 25deg. above horizon, nor do we even get proper darkness this time of year.

Imagined over the course of several moonless nights, because imagining through all that atmosphere, in nautical twilight, and past the meridian - into a light pollution dome, is already plenty bad enough without the Moon getting into the mix as well. Procured around 2 hours of usable data each night, give or take a sub or three.
I would have kept pounding away had the weather decided to keep cooperating with me, and since it appears it will remain uncooperative until the Moon is already back up, I decided to process the data on hand.

Dithered every second sub, stacked in DSS, Siril for background extraction, processed in Photoshop, StarNet++ along the way to prevent stars on SII and OIII going completely out of control, Topaz DeNoise for clean up. Stretched the living daylights out of the channels, then applied a separately, gently baby'ed Ha as luminance to bring the details back in, and tame the stars even more with their more controlled Ha profiles.

Will definitely feed it more light over the rest of the summer in bite sized, 1-1,5 hour pieces, and gonna reprocess once I reach 10h per channel.

Clear skies.

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.
