NGC 7293 - The Helix Nebula

The Helix Nebula, aka the Eye of God, is a large planetary nebula located in the constellation Aquarius. This object is one of the closest to Earth of all the bright planetary nebulae, with a distance of 655 light-years.

This planetary nebula was formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. The remnant central stellar core, known as a planetary nebula nucleus or PNN, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.

Our own star, the Sun, is expected to end up as a white dwarf and forming a planetary nebula. This is going to happen when its hydrogen fuel in its core is depleted, which is estimated to take place in 5 to 6 billion years.

This was imaged on the same nights as the Trifid, given the extra 2-3 hours after it got too low and to benefit from the rest of the night. This nebula doesn't rise above 35 degrees from my location, which made it a bit hard to capture with a poor performing mount, and very hard to process.

EDIT: I've mistakenly disabled comments on this image. Comments and feedback are, as usual, much appreciated.

Clear Skies!

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.
