LBN 515 - The Dark... Snapping Turtle?

Image of LBN 515 in Cepheus shot with my AT60ED w/ 0.8x reducer, Canon 600D, and CEM40. I think this may just be out of reach with my modest equipment, but wanted to give it a try anyways. The final image is kind of meh. But it does kind of look like the head of a snapping turtle splashing out of the water to grab something. On the plus side, I finally got my automation fully working, and have been able to shoot all night with autofocus, meridian flip, re-centering, and auto-park.

Shot over 4 nights in August/Sept 2022, with a total of 392 120-second light frames at ISO 800. Calibrated with 30 each darks, flats, dark flats. Initial processing in Astro Pixel Processor and finished in PixInsight.

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.
