Dumbbell Nebula (M27) in RGB/Halpha/O3/Hbeta

Dumbbell Nebula captured with ExploreScientificCLS Filter and Optolong L-enHance Filter., a combination of several frames taken with both filters with a OSC camera (QHY8L).

Processed with Drizzle in Siril. Channels were assigned:

CLS Red -> Red

CLS Green -> Green

CLS Blue ->Blue

Lenhance Red -> Halpha 656 nm

Lenhance Green -> O3 500nm

Lenhance Blue -> Hbeta 486nm

Siril than maps those Wavelength to colors...

Description: Additional RGB Data and modified post processing. Created six mono images:
R,G,B,Halpha (Red Pixels), O3 (Green), O3 (Blue). Aligned those images with nebulosity and used SiriL to Assign:
R -> R
G -> G
B -> B
Ha -> Ha (Siril creates an extra color with exact 656 nm ;-) )
O3(G) -> O3
O3(B) -> HBeta (I know its not exact, but I wanted a bit more blue in this channel)

Description: Final combination of Optolong LenHance and RGB (with CLS) Data.
The star colors are a bit weird still...

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.
