Rosette Nebula in 'OSC/L-eXtreme Hubble Palette'

Rosette Nebula (NGC2237 in Monoceros)
Recorded 01-26-2022, Camino Cerrito, Albuquerque, NM--My driveway
AstroTech AT72ED II / AT2FF Field Corrector / L-eXtreme Ha-OIII Filter / ASI294MC Pro Camera
EQ6R-Pro Mount
90x180s subs@120 Gain (4.5 hour integration)
Processed in Siril / Affinity Photo as 'Hubble Palette' (R=0.75*(R-B)+0.25*G, G=0.25*(R-B)+0.75*G, B=B)
Image reprocessed 7-28-2022(StarXTerminator, HLVG plug-ins)

This is a reprocessing of data recorded January, 2022. I found on YouTube (https://youtu.be/V3B1CY5LFco) a video on processing OSC images to give a Hubble look--it involves subtracting a bit of the blue channel from each of the red and green channels and adding a bit of green to red, etc. per the formula above. This was done in the PixelMath feature of Siril on a starless layer. A 'stars-only' layer was superimposed after this processing.

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.
