Cats Eye Nebula NGC 6543

Copyright: Mark Hanson


Explanation Via APOD:

The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But the composite image combines many short and long exposures to also reveal an extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the left, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552.

Moon 100% ILLUMINATED

Best access details:
https://www.astrobin.com/full/369097/0/?nc=user

The Moon is usually seen in subtle shades of gray or yellow
The different colors are recognized to correspond to real differences in the chemical composition of the lunar surface.
The blue tones reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while the orange and purple colors show relatively poor titanium and iron regions.
Technique: "false color"

Today I show you my most recent image. It is a narrowband Bi-Color representation of the Pelican region. I chose this as a target because I’ve always been fascinated with the strong structure in this area. It can also feel very 3D and displays a great amount of definition. This particular area lies in the constellation Cygnus and is a part of a larger nebula complex known as the North American Nebula.

Description: NCG 6888, about 5,000 light years from Earth, is also known as Crescent Nebula and is an emission nebula in the constellation Cygnus. This image was obtained using H Alpha and OIII narrowband shooting data, using the Cannistra Technique to obtain synthetic green. It shows the emissions of hydrogen and oxygen atoms, giving the image an intense red color and an interesting cyan blue mist. The tools I used are a Skywatcher 250/1000 f4; an EQ6 Mod Rowan Astronomy and a Moravian G2 8300. I processed the photo with Pixinsight 1.8

NGC 6960, the Veil Nebula, is a diffuse nebula located in the northern constellation Cygnus, the Swan.
It constitutes the visible parts of the Cygnus Loop, a supernova remnant in Cygnus. It is located at an approximate distance of 1,470 light years from Earth. The Veil Nebula has three main parts: the Eastern Veil, the Western Veil, and Fleming’s Triangle (Pickering’s Triangle).
