IC1396A Elephant's Trunk in SHO

My first SHO (aka Hubble) palette try. Imaged almost a year ago during moon nights in narrowband filters.

Main workflow steps:

- separate noise reduction for Sii, Ha, Oiii integrations in PI (using Jon Rista approach, see details)

- applying LinearFit to Oiii and channel combination into SHO, HistogramTransformation

- using Rick Stivenson ColorMask script to remove magenta tint, reduce green, boost cyan, ephasize yellow (see more info here)

- some other postprocessing in PI (local contrast, additional noise reduction, etc)

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.
