Vela Supernova Remnant: Bubbles within Bubbles

The Vela SNR is a rich hunting ground for interesting targets. In taking a previous image of the Blue Chilli, I was also keen to explore an image immediately to the west, which contains a remarkable - but faint - bubble of [OIII] emission.

With Vela stating to sink in the west at an increasingly early hour, I tried my best to capture the [OIII] during "moon down" times in this lunation's first quarter.

Overall I am happy with the result, but hopefully the skies will be clear for 3rd quarter when I can get some more [OIII] signal to further bring out the remarkable detail in these beautiful [OIII] shells.

I have included a starless version which helps to show off further the fine structure in the gas.

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.
