NGC 6960 Salvaged (Dan Kusz)

NGC 6960 Salvaged

This was the first and only OSC deep sky image I have taken. I took it in the summer of 2019 when I was just getting back into deep sky photography. I had not acquired a cooled camera yet and was using an old modified 600d. It was 25 degrees Celsius on the two nights I imaged. At that time of year, being 50 degrees north, I also never get astronomical darkness. I had everything against me except clouds. The data was so bad I was unable to process anything at the time. With bad weather for weeks recently, and new processing techniques, I tried to salvage what I could. The back ground is still blotchy, but I can live with it. I have attached a single raw sub frame so you can see how bad the data set was!

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter. While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements.

NGC 6960 - The Witch's Broom Nebula Also known as Western Veil, The Finger of God, The Lacework Nebula, The Filamentary Nebula, and Caldwell 34. The bright star in the image is 52 Cygni. The colours are from emission of Hydrogen, Oxygen and Sodium gas.

Thank for looking!

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.
