The Vela Supernova remnant (GUM 16) in GUM 12, an HII region 450 parsecs away, is a greatly expanded supernova remnant found in the constellation Vela. The object is huge, spanning 8 whole degrees. This of course covers only a tiny portion of it.

I ended up calling it the Bubblegum Nebula because it totally looks like "bubblegum remnant". It's certainly not its popular name.

This image is my deepest image yet, sporting a little more than 13 hours of total exposure time. Still, I had to apply some heavy noise reduction, the remnant is quite dim, but rich in structure and really awesome to look at.

My aim was 20 hours, but it doesn't look like I will be able to reach my goal this season.

I'm still improving on my processing here, namely noise reduction and local normalization, because one of my sessions ended up quite misaligned and it shows on the final stack. As I improve on it I will upload better revisions.

The Ha B&W version is worth a look as well.

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.
