NGC 6979 - Pickering's Triangle

This is small area of the Veil nebula called Pickering's Triangle. Located in the constellation Cygnus, the Veil nebula is the remnants of a star that exploded in a supernova roughly 10,000 years ago. It is estimated to be a relatively close 2,400 light years away from us.

When the event occurred, it would have been as bright as a crescent moon and visible for several weeks for humans to view and wonder what was happening up there. From our viewpoint today, it has expanded to be the size of roughly eight full moons. The beautiful ionized Hydrogen and Oxygen continues to expand from the center and will continue to fade away. The star that was the source of the explosion was about 20 times the mass of our sun.

It has been a fortuitous string of clear nights out at SRO, allowing me to capture over 30 hours of data on this target. Although it may look like it, there was very little sharpening applied during processing. Just a light application of BXT. I used GHS to bring out the dimmer background features whilst protecting the brighter features from becoming over stretched. I am still dealing with tilt on this scope frustratingly. It will take one more trip out to the observatory next month to fix that once and for all. Other than that the rig is running beautifully. All images are now being shot unguided.

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.
