Horse Head Nebula and friends in (HaL)RGB

I have collected the RGB data for this image with my CMOS ZWO ASI2600 colour camera during 3 nights, around 6 hours of total exposure. Then, I blended the extracted Luminance channel with the Ha data previously collected with a QSI683 CCD mono camera.

This project had a few challenges: The combination of CMOS and CCD data, the combination of colour and mono data, as well as the different sampling and sensor size :-)

PixInsight was used for the pre-processing and post-processing. The blend of Ha and Luminance data was critical in order to maintain colour information. A blended Red-Ha channel was also used for this purpose.

Please feel free to comment, I would like to discuss the workflow approach in order to apply final enchantments :-)

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.
