IC 1396. aka Elephant Trunk nebula (Zoom @ 1305mm)

The Elephant's Trunk Nebula revisit: @ 1305mm zoom shot vs 550mm widefield view
It is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim.
Note: final image is dark, and best seen on a laptop or iPad screen, will try Hubble Palette next to bring out more details
Equipment used: Celestron Evo 8" SCT on AVX mount, with ZWO 294MC Pro main cam and ZWO 120mini guidecam, 60mm guidescope, ASI Air Plus, Optolong L enhance filter, ZWO EAF, Bathinov mask, dew heater straps and powered by two Jackery units. Last night, epic data acquisition for 4 hours, yielded 2 full mosaic targets worth of data, and for Elephant Trunk nebula:
11 x 180sec light subs (panel#1)
11 x 180sec light subs (panel#2)
30 darks and 30 auto flats
Stacked and Mosaiced in Astro Pixel processor. Post processing done in Pixinsight, with touch-ups in Paintshop pro for clarity and vibrancy. Two versions, original stars deemphasized and Stars-less, enjoy!
Note: Very slight star trails due to possible guidescope flexure, DST vs SDT mismatch, or guiding rate (1X vs 0.5X) mismatch. Troubleshooting is underway on an earlier post and will update with resolution results.

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.
