Dark Nebulae and IC1396

I continue to focus mostly on dark targets in broadband, and this image of the Elephant Trunk in Cepheus obviously gets the focus on the dark nebulae and dust as much as the nebulosity that narrowband images bring out.

Revision C/D - I'd promised to reprocess this at some point, as I couldn't handle the gradients very well with all those stars and the nebulosity getting in the way, and had resorted to Pixinsight's ABE in the initial versions which didn't work very well. I've since learned to carry out DBE on a starless image, and this makes it much easier to manage targets like this. This has allowed me to be a bit more aggressive with my curves to bring out the nebulosity and a bit more contrast.

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.
