Sh2-119 (Clamshell Nebula) in Cygnus, with unfiltered Bortle 1 RGB plus NB data

I shot unfiltered RGB data last year on this DSO under Bortle 1 skies with my OSC camera, but was never happy with the final result. The colors were beautiful but the signal was weak on the nebulosity and there wasn't a lot of data. I decided to add a bunch of narrowband data using the L-eXtreme this year to the data set, and it made a huge difference in terms of signal and also noise, despite the fact that the NB data was obtained from by backyard under Bortle 5/6 suburban skies. The colors on the DSO have been blended together in a roughly 50:50 ratio and the luminance is about 90:10 NB:RGB. The stars, of course, are 100% Bortle 1 RBG data. I hope you enjoy the result as much as I do.

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.
