Widefield Elephant Trunk in SHO

First mediocre-ish attempt at the SHO palette.

Shot this target over four nights with my debayered Canon 60D, Rokinon 135mm f/2 lens, and iExos-100 mount. 5 minute subs at ISO 800 with Astronomik 6-nm H-a clip filter, and 10 minute subs with 12-nm OIII and SII clip filters. Pretty surprised that the iExos could handle 10-minute subs, but it did great. Then added in a splash of RGB stars from a separate integration.

Stacked and aligned in Astro Pixel Processor, then stars removed and halos cleaned up via Starnet++, and composed into RGB in GIMP.

Thanks for looking, and feedback welcome and appreciated! Did I overbake the colors?

Description: I applied some much needed noise reduction to the background and cleaned up some of the wonky stars. I'm not a big fan of noise reduction, but in this case I think it improved the overall 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.
