Eastern Veil Shockwave (Olly Barrett)

Eastern Veil Shockwave

I wanted to show the might and majesty of the Eastern Veil Nebula Supernova Remnant...
The source of the supernova, which occurred between 10,000 and 20,000 years ago, was a star 20 times more massive than our own Sun...
At the time of the event this phenomena would have appeared brighter than Venus in the sky and been easily visible during the daytime...
The Eastern Veil Nebula has recently been re-evaluated as 2400 light years from Earth...
The Veil Nebula is expanding at a velocity of approximately 1.5 million kilometres per hour... Some shockwave!

The image is a complete re-edit of some Esprit data I took in the summer with some added RGB and extra Ha and Oiii I've taken on an opportunity basis.
Care was needed during processing to preserve the nebulosity in the Ha stream at the top of the Veil, without the additional 600s Ha exposures and RGB subs this would not have been possible…
I decided to frame this image at an unconventional angle for this target to try and give an impression of the expansion taking place...

Clear Skies!

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.
