An Artist’s Impression of The Helix Nebula - NGC 7293

The Helix Nebula (NGC 7293) is a large planetary nebula located in the constellation Aquarius. The Helix Nebula’s estimated distance from earth is about 215 parsecs or 700 light-years. The Nebula has sometimes been referred to as the “Eye of God” in pop culture because of it’s eye like appearance. It was the first planetary nebula discovered to contain cometary knots, which can be seen as globs with tails around the center of the “pupil”. Astronomers have sense discovered similar structures in other planetary nebulae and use the Helix Nebula as a base case for comparison. There are more than 20,000 cometary knots estimated to be in the Helix Nebula. These knots remain somewhat of a mystery to astronomers.

THE SIGNS AS NEBULAE

Aries: The Eagle Nebula

Taurus: Spirograph Nebula

Gemini: Medusa Nebula

This is Pismis 24-1 (HDE 319718), a region with spectacular diversity, beginning with its open cluster of neighboring stars, called Pismis 24. Together, they are centrally located within the diffuse nebula NGC 6357, which is located approximately 8,150 light-years from Earth in the constellation of Scorpius.

Our Galaxy in 340-million pixels

This region of the milky way spans the sky from the constellation of Sagittarius to Scorpius. In this image we see the dusty lane of our Milky Way running obliquely through the sky, dotted with remarkable bright, reddish nebulae, such as the Lagoon and the Triffid Nebulae, as well as NGC 6357 and NGC 6334. This image was taken by Stéphane Guisard, an ESO engineer and world-renowned astrophotographer, from the home of ESO’s Very Large Telescope, one of the best on the planet.

California Nebula with added SII 

Added some more data to my image of the California Nebula. Only my 2nd narrowband image so still learning but ive mapped the Ha to Green and Blue and the SII to Red, no OIII was captured. This object has moved out of my FOV now so its time to move on and image something else.
