The Gum Nebula (Gum 12) is a nebula that covers approx 40° in the constellations Vela. It lies approx 1300 lightyears from the Earth.

These thin strands of nebulosity are the remains of a star which ended its life as an enormous supernova explosion around 11,000 years ago.

It got its name after its discoverer, the Australian astronomer Colin Stanley Gum(1924–1960).

Exposures: 55 x 5 minutes with OIII- and 48 x 5 minutes with Ha-filter,

using a FLI 16801 Fingerlake CCD camera on a Takahashy FSQ 106 with 530 mm focal length on a Paramount ME mount.

All images were exposed remotely on the Siding Spring iTelescop Farm at T08.

Between January 27th and February 21st 2017.

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.
