NGC 7293 The Helix Nebula in RGB

The Helix Nebula (NGC 7293) is located in the constellation Aquarius is one of the closest planetary nebula to the Earth at a distance of around 655 light-years.
It has an apparent magnitude of 7.6 and is about 25 arcminutes in size. The Helix Nebula has sometimes been referred to as the Eye of God or the Eye of Sauron.
The remnant central stellar core of the planetary nebula is destined to become a white dwarf star and the glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.

I can't waste a clear new moon on NB and this was very well placed for some good long RGB runs.

Summers coming and the cold nights will be missed.

One night was pretty poor due to extinction from hazard reduction smoke. Better now than with a 'breeze' behind it in summer ...

I got to keep almost 8 out of 10 hours overall so with some good seeing no complaints.

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.
