NGC 7293 a.k.a. Helix Nebula
…………………………..
Helix Nebula, also known as the Eye of God, is a planetary nebula that was discovered about 200 years ago by German astronomer Karl Harding and can be found at 650 light-years from Earth, in the constellation of Aquarius. Specialists believe that Helix appeared due to a star relatively similar to the Sun, a star that reached the last stage of its existence and began to release large amounts of energy and gas in the outer space. The calculated diameter of this nebula is almost 3 light years, and the expansion speed exceeds 20 miles / sec.
In the northern hemisphere ( 45 degrees ) Helix can be observed / imaged only during the summer, August being the best month for this, but because it does not rise much in the night sky, those passionate about astrophotography and / or visual observations must use locations with a good opening towards the south, and away from the light pollution of the big cities.

The Helix Nebula, also known as The Helix and also referred as the Eye of Good or Eye of Sauron. NGC 7293, is a large planetary nebula located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824. This Planetary Nebula is one of the closest to the Earth. The estimated distance is about 215 parsecs (700 light-years) closer than the Great Orion Nebula. It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.
The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. 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.

Another Farewell
Interplanetary Travel
It's time to part. My last day on the snow planet. I have completed my research on the rather cold and quiet planet. I couldn't find any trace of plutonians on this planet. However, it was a different experience for me. It was impossible not to be enchanted by the silence of the planet. However, the fact that it consisted of cold and high mountains made this planet far from being a livable planet. Maybe millions of years ago, there were civilizations that lived on it. But now I could not find any traces of civilization. I have completed my preparations for the planet I will visit next. I will start my space travel soon. As you read this note, I will be floating in outer space on my new course. I placed the rock, dust, water and plant samples I collected from this planet next to the samples I collected from other planets. And again, I left a memory of myself behind. I do this on all the planets I visit. A photo of myself and a sample of my hair. I don't know if anyone will find the box I left. But I will continue to do this anyway. Maybe there is someone looking for me, just as I am looking for the Plutonians. Maybe the reason I do this is because I'm alone.
Thank you for accompanying me on this adventure. We will be together again in the exploration of a new planet. I'm pretty excited for the next planet. I have been observing the next planet I will visit for some time now. The most important finding that excites me is that that planet has an atmosphere that is very suitable for life. And unusual mountains. I can't wait to set foot on that planet and explore. I hope I reach that planet without any problems. See you in new discoveries and new adventures.
Keep following me.

Hi Folks,
NGC 7293, The Helix Nebula, is a planetary nebula - basically, a star that has exploded off its outer layers) located 455 light-years away in the constellation of Aquarius.
This is another image resulting from the trove of data collected during the incredible stretch of weather we just had in western NY November 5-8, 2021.
This image was shot with my Astro-Physics 130mm Telescope Platform with the IOptron CEM60 and the ASI2600MM-Prop Camera. a little more than 4.5 hours of LRGB and Ha data was captured.
This is a really tough image for me to capture as it rides very low in the sky here, and it is positioned such that I can only get about 90 minutes on target each night due to the trees on my property.
Because of these challenges and others, I knew this would be a data set plagued with many issues, so I put off working on this while the others collected at the same time were processed first.
As I dug into the data further, I found even more problems, some due to clouds and sky conditions, some due to SAM (Stupid Astrophotographers Mistakes).
So I had to work on my Pixinsight skills to get something useful out of this image. I am not at all thrilled with the final result - while it is marginally better than an earlier effort I made on this target, it fell well short of what I was shooting for. But - I share all of my images, good and bad, on my website because both are part of the Journey - and perhaps some learnings can be made from each.
The story of the image and its processing can be seen on my website at:

The Helix Nebula is a large planetary nebula located in Aquarius. It’s faint and difficult to capture detail, requiring dedication to gather enough time on the target. I shot the Helix a year prior, at the same star party, and was intent on bettering the result this year.
I spent 2 nights fighting against nature, and although the sky was clear the wind never really died down. I gathered over 7 hours of data but deleted 50% due to elongated stars. This is the result I’m left with, a rather dim and slightly noisy Helix but still an improvement on my 1st attempt.

The “ Eye of God” or The Helix Nebula (NGC 7293) is a planetary nebula located in the constellation Aquarius, at about 650 light years from the Earth. Discovered by Karl Ludwig Harding in the early 19th century, Helix is one of the closest of all the bright planetary nebulae. The central star of the Nebula, a white dwarf remnant of the star that exploded about 10,000–12,000 years ago, gives the resemblance of an eye. When a star like the Sun runs out of fuel, it expands and its outer layers puff off, and then the core of the star shrinks. This phase is known as a "planetary nebula," and astronomers expect our Sun will experience this in about 5 billion years. The blue-green glow in the centre of the Helix comes from oxygen atoms shining under effects of the intense ultraviolet radiation of the 120 000 degree Celsius central star and the hot gas. Further out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent.
I captured this view of NGC7293, aka the Helix nebula, aka "The eye of Sauron", using a remote telescope.
As my equipment is not with me at the moment, I had to find another way to combat astrophotography withdrawal.
I could rent some time on a 60 cm telescope in Chile.

A planetary nebula, the "Helix" was formed starting only about 10,000 years ago from gases shed by a dying star, with the outer layers expanding somewhat faster than the inner layers. The remaining core of the star is so energetic that it excites the expanding the gases, causing them to glow.
The Helix Nebula is often noteworthy for its resemblance to an "eye in the sky" from our vantage from Earth; it's alternately referred to as the "Eye of God" and even "The Eye of Sauron". In reality, though, it is thought to be shaped as a prolate spheroid, somewhat resembling a football.

A re-processed image of my data of The Helix Nebula (NGC 7293), also known as the "Eye of God".
This is a planetary nebula located in the constellation Aquarius. One of the closest planetary nebulae to Earth being 655 light years away.
This image was exposed through a 8" SCT at 2032mm focal length using a astro-modded and cooled DSLR.
I didn't get as many subs as I wanted due to staring imaging this object so late into the season and literally only having a couple of hours of exposure time each evening before it was obscured by my house, hence the slightly noisy image.
Eye in the sky. This is the Helix Nebula (NGC 7296) found in the constellation Aquarius. One of the largest and closest planetary nebula in the sky. Planetary nebulae are dying stars that expel all its atmosphere leaving its hot core (central star) exposed. The intense blue at the center of the 'eye' is from oxygen atoms shining under effects of the intense ultraviolet radiation of the exposed core star. Taken with a Ceravolo300mm astrograph, 1470mm focal length. 10 hours of LRGB with hydrogen-alpha and Oxygen (OIII) filters.

« L’Oeil de Dieu » ou la Nébuleuse de l’Hélice 🔭
.
Cette nébuleuse, dite « planétaire », semblable à un œil humain, est formée par une étoile mourante… Elle est située dans la constellation du Verseau à quelque 700 années-lumière de la Terre.
.
Elle se présente comme deux anneaux entrelacés, mesurant au total presque 6 années-lumière de diamètre… On pense qu’elle s’est formée, il y a 12 000 ans. Les gaz et matières expulsés de l’étoile centrale, s’étendent à plus de 32 km à la seconde… :)
.
Elle est très difficile à observer à l’œil nu en raison de sa faible luminosité, et sa position dans le ciel. Dans l’hémisphère nord, et dans le nord de la France, elle ne s’élève qu’à 18° dans le ciel. À cet emplacement dans le ciel, les perturbations atmosphériques et la pollution lumineuses sont très présentes. Ce qui en fait une des nébuleuses les plus difficiles à imager.
.

Instead of looking like a spiral staircase, our perspective makes the Helix Nebula look more like a giant eye In the sky - earning additional names like "Eye of God" and "Eye of Sauron". Way back around 1824, Karl Ludwig Harding discovered the Helix Nebula and became the first person to discover a planetary nebula that contains something called "cometary knots". These knots of nebulosity appear in the Helix Nebula as little pillars of pink reaching from the outer ring into the blue center (barely visible in this image). It's estimated that the Helix Nebula has around 40,000 of these cometary knots.

The Helix Nebula, sometimes referred to as the "Eye of God". Taken with a Nikon D810a in a Televue NP101 telescope. 8 hours of Ha and 3.5 hours of RGB.
The Helix Nebula (NGC 7293) is a large planetary nebula located in the constellation Aquarius, approximately 650 light-years away from Earth. It is one of the closest and best-known examples of this type of nebula. The nebula's stunning, eye-like appearance has made it a favourite target for amateur astronomers and astrophotographers.
I tried this target many years ago and wanted to have another go and do it some justice. I grabbed a bucket load of data to see what the result would be. I love the teal colouring of the core. This wonderful colour is often removed during the processing stage, and this is something I wanted to retain in the final rendition. It’s such a lovely colour.
If you look closely, many tiny galaxies can be found throughout the field. There is even an interacting galaxy around the 3:30-4:00 o’clock position from the central star of the planetary (right where the dimmer nebula is fading to the background). The colourful stars add a nice balance.
Key Characteristics:
Shape and Appearance: The Helix Nebula resembles a giant, colourful eye, with a bright central region surrounded by a faint, extended halo. The inner part of the nebula is dense and consists of gases such as hydrogen and oxygen, while the outer regions are more diffuse.
Central Star: At the heart of the Helix Nebula is a white dwarf, the remnant of the star that created the nebula after shedding its outer layers. This white dwarf is extremely hot and emits intense ultraviolet radiation, which ionizes the surrounding gas and causes the nebula to glow.
Size and Structure: It spans about 2.5 light-years across, and its physical structure is made up of complex knots of gas, sometimes referred to as cometary knots. These knots are dense, molecular clumps that were shaped by the intense radiation from the central star.
Colors: The vibrant colors of the nebula, often seen in images, come from the different elements present. Hydrogen emits red light, while oxygen emits a greenish-blue hue.
Formation: The Helix Nebula was formed when a dying star, similar to our Sun, ejected its outer layers into space at the end of its life. The remaining core became the white dwarf at the center.
Scientific Importance: As one of the closest planetary nebulae, the Helix Nebula provides astronomers with a valuable opportunity to study the late stages of stellar evolution. It offers insights into how stars like our Sun will evolve and eventually die.

This beautiful nebula is called Helix nebula (NGC 7293) or Eye of God and sometimes called Eye of Sauron. Its the closest planetary nebula to the Earth about 450 light years in constellation of Aquarius. It is a dying star that blown out its outer shell. The remanent star in the middle of the nebula is a white dwarf that reaching its end of life and nearly finished the nuclear fuel. The colors of this object is due to presence of the very hot white dwarf that energize the central part of the nebula in green from the ionized Oxygen. The outer part is Hydrogen gas glows in Red. Just imagine that, those gases are expanding at rate of 40 km per second.

From Wiki; The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula located in the constellation Aquarius. This object is one of the closest to the Earth of all the bright planetary nebulae. The distance is 655±13 light-years from Earth. The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture, as well as the "Eye of Sauron". The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. The remnant central stellar core, known as the central star (CS) of the planetary nebula, 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.
Also known as the 'Eye of
God' or 'The eye of Sauron', The Helix Nebula is a planetary nebula located in the constellation Aquarius, lying at an approximate distance of 700lyrs away and a radius of 3lyrs across.
What we are seeing in this image is a star at the end of it's evolutionary process on its way towards becoming a white dwarf.
The Nebula has an apparent magnitude of 7.5, but is not visible to the naked eye easily, due to it's low surface brightness.
