IC 1396 - Elephant Trunk Nebula

Revision title: HOO + SII blend

IC 1396 in narrowband from London.

Shot over three nights in August, September and October, with almost 19 hours of acquisition.
First light for both my new ASI2600MM and Chroma narrowband filters.

This new 2024 version, aside from using new modern tools such as BlurXterminator and NoiseXterminator, makes use of a different technique illustrated by Adam Block.
The image was first rendered with an HOO palette, then SII data was added back with a yellow tint.

I really like this new output, the colours are quite rich and well balanced, especially compared to the older HOO and SHO versions.

The other (older) versions were processed using three different palettes: SHO (classic "Hubble palette", with more contrast), HOO (using only oxygen and hydrogen filters, more realistic colours), and HOS (middleground between the two).

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.
