NGC 6914 - Blue Gems of Cygnus

This was shot at a club star party at Hancock Field Station operated by OMSI. It was a a beautiful site with great conditions for the nights that we were there. I look forward to going back again in the spring.

Sadly, though I shot the same target for both nights, the first night of data was corrupted and unusable. Thankfully, the dark skies saved me and provided a strong signal to work with.

Workflow:
Pixinsight:
Separate RGB channels
LinearFit on R
StarAlignment thin plate splines, G as reference
Recombine RGB channels
NoiseXterminator through luminance mask to protect highlights
MaskedStretch
StarXterminator
Save Starless and Stars for PS
Separate RGB channels
Save R for PS
Create PseudoLuminance from 40% R, 30% G, 30% B, save for PS
PixelMath - R=R, G=R*.6+(B*.5+G*.5)*.4, B=B*.5+G*.5
Save StarlessNB for PS

PS:
Layers:
Stars (screen)
Vibrance
Curves
PseudoLuminance (luminance)
R (overlay)
StarlessNB (color)

Some levels adjustments on most image layers
CRF on StarlessNB
Unsharp Mask on PseudoLuminance
Blend down opacity on PseudoLuminance
Minor adjustments with vibrance and curves adjustment layers

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.
