Vela SNR - Spiral Flame - 2018

This object is a part of the Vela supernova remnant, located 800 light years away in the southern constellation of Vela. It is estimated that the supernova exploded approximately 12,000 years ago. The Vela supernova remnant overlaps the Gum supernova remnant, and the two are among the largest and brightest features in the X-ray sky. The Vela SNR is one of the closest supernova remnants to earth.

The region captured in this image shows a spiraling helical length of twisting OIII filaments. A large patch of hydrogen provides the flame. An interesting bright hydrogen nebula is seen at the lower left of the image.

My favorite part of the image are the faint reddish Ha wisps which follow some of the leading arcs of the greenish OIII filaments.

The weak strength of these emissions, combined with the low declination of the target from my viewing site, makes this a tough object for me to capture.

The refractors!

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.
