M1 - NGC 1952 - Taurus A: emulated RGB with HSO data

I finally got a bunch of OIII data to be able to composite an HSO image. I decided for HSO since the SHO colors were really not the way I expected it. The stars were obtained by using my often used "natural" RGB from S, H and O:

R= 45% Ha + 55% SII

G = 10% SII + 20% Ha + 70% OIII

B = 10% Ha + 90% OIII

The image was processed traditionally, hence no color manipulation in any form. Steps included: Deconvolution, DBE, ABE, low stretch, create RGB stars from low stretch, more stretching, create starless images, clean starless images with stamps, combine starless images into HSO, create masks with range selection, emphasize nebula with range mask, overlay starless image with RGB stars, Pixel Math stretched HSO (25%) with obtained result (75%).

Expected a bit nicer color scheme, but since this was the result without any color manipulation I left it as is.

Another example that one can do good narrow band images with an achromatic telescope.

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.
