The Ring Nebula (James R Potts)

Celestial hemisphere: Northern · Constellation: Lyra (Lyr) · Contains: IC 1296 · M 57 · NGC 6720 · Ring Nebula

The Ring Nebula

This is my first time to capture the Ring Nebula. This is quite a small target even for 7.5" aperture, but I liked the star field so I left the wide FOV and then added a close up. I never realized there was a ring around the Ring Nebula. This planetary nebula is the glowing remains of a sun-like star, the tiny white dot in the center of the nebula. This star is a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra and was discovered by the French astronomer Antoine Darquier de Pellepoix in 1779. According to the NASA website, the deep blue color in the center represents helium, the light blue color of the inner ring is the glow of hydrogen and oxygen, and the reddish color of the outer ring is from nitrogen and sulfur.

In close aparent view is IC 1296 a 15th magnitude Sprial Galaxy that is around 260 million light years away.

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.
