Veil Nebula Ha mosaic (David Ellison)

Veil Nebula Ha mosaic

This is a full resolution 6 panel mosaic of the Veil Nebula in Cygnus done in Ha.

The Veil Nebula, originally called the "Bridal Veil" is an enormous remnant of a supernova thought to have happened 5000-8000 years ago. Some suggest there was a previous supernova, about 18,000 years ago. The filaments are thought to be the shock wave of the more recent explosion interacting with the wreckage of the previous explosion. The Eastern edge of the Veil emits brightly in X-ray which is consistent with a shock wave interacting with previously existing material.

The Veil occupies an area of about 3 degrees, so it would take about 5-6 full Moons to span it in each direction, or about 25-30 full Moons to cover the entire nebula. It spans approximately 100 LY and is about 1500 LY distant.

This image is large, 5460X6799 pixels, it takes a little while to download the full sized image but it is worthwhile. There is a lot of detail particularly in the faint nebular bands in the upper left and mid way down on the right side. On the right, half way down is the the Witch's Broom with the magnitude 4.2 star, 52 Cyg. At the top right is Pickering's Triangle. The left side is the Eastern Veil.

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.
