C1396 - The Elephants Trunk - this time with extra Ha!

A few days ago I shared an image of IC1396, also known as the Elephants trunk. It was one of my very first LRGB images after doing a year of One Shot Color Camera work. I went back a couple of nights later and collected my first narrowband data for this object. I captured 10x6minute exposures at an elevated camera gain of 200. Then I processed that image and combined it with my previous LRGB data. Since my Ha was a 7nm band slice of the red region - I would have expected that it would greatly increase red saturation and detail - and it did just that. While mono camera imaging is more work I can see its attraction!

Here are the image details:

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.
