IC 1396 - Elephants Trunk Nebula in SHO

C 1396 - Elephant Trunk Nebula - June 2022
Planewave CDK 12.5 - AIS6200MM
A-P 1100 GTO AE, Antlia Pro 3nm NB filters
H,S,O: (18,15,16 x 300s exposures, Bin 2, Gain 200)
Total Integration Time = 4.1 hours
The Elephant Trunk Nebula is a patch of cool, relatively dense dust and gases within the IC1396 nebulosity complex within Cepheus.
The complex shapes arise from the gases collapsing to create new stars, that then are blown away from the very stars that the gases created. This one supposed looks like an Elephant's trunk.
The false colours employed here are used according to Hubble Palette and represent the relative emission intensities of hydrogen, and oxygen and sulfur ions. In this case, the gas and dust is so dense in places that it blocks any light from behind it and is only visible in silhouette.
The Elephant trunk is 2400ly away and is over 20 ly long
This was my second test at using high gain on my camera to determine if a good NB image of a bright nebula could be obtained within one short summer night.

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.
