NGC 6914 region: emission and reflection nebulae in Cygnus

NGC 6914 is a complex of emission and reflection nebulae in the constellation Cygnus. The reflection nebulae (VDB 131, VDB 132, and Parsamian 22) are illuminated by stars in the Cygnus OB2 association, surrounded by a sea of swirling hydrogen emissions, including LBN 273. The dark nebulae LDN 897, 899, and 900 provide stunning contrast.

This image is a LHRGB composite taken over five nights to yield slightly under 8 hours of data total. The luminance channel is a combination of the Chroma L and 5 nm H-alpha filters. The red channel is a combination of the Chroma red and H-alpha filters. Processing was done in my usual suite of software, with GIMP serving as the main workhorse. I used Topaz AI for noise reduction, but not sharpening. No sharpening was necessary on this image, except that I used modest deconvolution on the stack of short luminance subs to tighten up the stars a bit. I had to make a decision on whether to use stars from the L stack or the Ha stack, and I ended up going with the L stack, despite the fact that some of the brighter stars were overexposed. I didn’t want to lose any of the fainter stars, and the Ha filter does attenuate the light from the fainter stars pretty severely.

Overall, I’m loving the Chroma LHRGB filters, but I just wish I had more clear nights to use them since I received them last fall. This entire project was shot between passing clouds, with an average of only 1.6 hours of data for each night I set up my gear.

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.
