This is a planetary nebula in Lyra.

It is a sun about the size of our sun that has burned through all of it's hydrogen and blown off its outer layers as a last gasp. In the process new elements (He, O, Si) have been formed. This nebula is about 1 light year across and is locate about 2600 light years from earth. http://www.edbianchina.com/apps/photos/photo?photoID=24084175 24084175 Cropped Saturn Nebula http://www.edbianchina.com/apps/photos/photo?photoID=11617247 11617247 Cropped Owl Nebula http://www.edbianchina.com/apps/photos/photo?photoID=24084176 24084176 Closeup Saturn Nebula http://www.edbianchina.com/apps/photos/photo?photoID=11617308 11617308 The Eskimo Nebula The Eskimo Nebula (NGC 2392), also known as the Clownface Nebula,[4] is a bipolar double-shell[5] planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments. NGC 2392 lies more than 2,870 light-years away and is visible with a small telescope in the constellation of Gemini. http://www.edbianchina.com/apps/photos/photo?photoID=76163635 76163635 NGC 7662 - Blue Snowball Nebula NGC 7662 otherwise known as the Blue Snowball Nebula is a planetary nebula located in the constellation Andromeda. The distance to this nebula is not known with any real accuracy. According to the Skalnate Pleso Catalogue (1951) the distance of NGC 7662 is about 1,800 light years, the actual diameter about 20,000 AU. In a more recent survey of the brighter planetaries, C.R.O'Dell (1963) derived a distance of 1,740 parsecs or about 5,600 light years, increasing the actual size to 0.8 light year, or nearly 50,000 AU. It has a faint central star that is variable, with a magnitude range of 12 to 16. The central star is a bluish dwarf with a continuous spectrum and a computed temperature of about 75,000K. The nuclei of the planetary nebulae are among the hottest stars known. In the photo I provide a reference image from a large telescope and a close up. This was taken with my 9.25 SCT using a Lumicon Giant Easy Glider. My first attempt. http://www.edbianchina.com/apps/photos/photo?photoID=97431945 97431945 PK 119-6.1 Not very exciting but it is the only image I could find of this object. I would bet that is not true but I can't find any others. This is a very small planetary nebula and hard to resolve. It is also very faint. image taken with the 9.25 SCT and the QHY8. http://www.edbianchina.com/apps/photos/photo?photoID=103024990 103024990
