IC348 SHO Dynamic Narrowband Combination

Revision title: IC348 SHO Dynamic Narrowband Combination

According to Andre B. [ https://telescope.live/blog/dynamic-narrowband-combinations-pixelmath ] who in turns referred to The Coldest Night [ https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/ ] narrowband channels integration and combination is subjective and could not coincide with a simple channel combination of Sii Ha and Oiii masters within an RGB implementation, as also suggested by Edoardo Luca Radice during CEDIC 2019; cfr. “Creating near true color images for nebulae from narrow band data using PixInsight” [ http://www.arciereceleste.it/tutorial-pixinsight/cat-tutorial-eng/110-cedic19-art?fbclid=IwAR0ybmyfZCC8G2ykfgDavTpBY7tEjE_DhJOAeT_QM5gZpKSvAfSmiNOoznw ]In my approach and attempt I used PixInSight > Pixelmath formulaR = (Oiii^~Oiii)Sii + ~(Oiii^~Oiii)Ha
G = ((OiiiHa)^~(OiiiHa))Ha + ~((OiiiHa)^~(OiiiHa))Oiii
B = Oiiito generate IC348 integration and postproduction.
In my approach and attempt I used PixInSight > Pixelmath formula

R = (Oiii^~Oiii)Sii + ~(Oiii^~Oiii)Ha
G = ((OiiiHa)^~(OiiiHa))Ha + ~((OiiiHa)^~(OiiiHa))Oiii
B = Oiii

to generate IC348 integration and postproduction.

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.
