Melotte 15 - Baader UHC-L Booster

My second image of the night, with my UHC L-booster filter. Here the septum of that famous nebula, leading to those extraordinary pillars embedded in the bright open cluster Melotte 15. I pulled up the blue a little in this one to help differentiate the OIII interplay with Ha.

Captured in Stellarmate (Ekos) on my RPi4, calibrated and stacked in ASTAP, processed in Siril, with background extraction, photometric CC, Starnet removal, Astro sharpening of the starless image, recomposition with RGB stars and final noise reduction.

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.
