NGC 6974 and NGC 6979 - Luminous Knots in the Veil

NGC 6974 and NGC 6979 are luminous knots of nebulosity found in the Veil Nebula/Cygnus Loop. While not as famous as the nearby Fleming's triangular Wisp, these smaller structures are intriguing targets on their own accord.

While processing in PixInsight, I took advantage of Russel Croman's latest StarXTerminator script with AI Version 10, now with the Unscreen Stars function, which preserves the original star colors better than the prior StarMask generated stars.

The starless image was also de-noised with NoiseXTerminator, which seems to be giving better end results than MultiScaleLinearTransform and TGV Denoise combined. Sharpening of the nebula was done with some Deconvolution followed by UnSharpMask, then a touch a LocalHistogramTransformation.

Finally the original stars were reduced in size a bit with MorphologicalTransformation , and then returned to the image by blending in with PixelMath. Mr. Croman's new tools are simplifying the processing workflow quite a bit, helping generate higher quality final images in lesser time.

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.
