The Cheerio Nebula (NGC 6337) within Diffuse Nebula (RCW 123) in HaLRGB

The Cheerio Nebula is a tiny bipolar toroidal planetary nebula in the constellation Scorpius about 5,200 light-years from Earth. It is situated within a vast field of background hydrogen nebulosity and its shape resembles a piece of the breakfast cereal Cheerios hence the name. Although such a small object in my field of view, I was pleased to capture the rings (approx 0.9 arcminutes in diameter) some containing bright cometary knots and the binary pair of stars in the centre.

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.
