Elephant Trunk - IC-1396

88 subs at 60 s from Bortle 9 sky. My processing workflow: Calibration and integration using APP. Pixinsight for Color Calibration and automatic background extraction. Back to APP to remove light pollution. At that point I was pretty satisfied with the image. But ... very minor cropping with PS to remove the artifact on the edge due star alignment. Tweaked the curve, saved as Jpg and used Topaz denoise for the final touch. This little scope can do wonders! Guiding was not the best. I don't know if it was seeing (did I say Bortle 9 and a bit of wind), or just the AVX. It ranged between 0.8 and 1.8. All in all, I am satisfied with the results. Thanks for visiting and please critique.

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.
