Planetary Nebulae

The Egg Nebula: Believed to be a proto-planetary nebula, representing the transition to the planetary nebula phase. It is part of Cygnus, although distance is uncertain it is probably 3000 light years away

Ring Nebula, M57: Located in Lyra about 2,300 light-years away from Earth. It is an example of a bipolar nebulae. 

Medusa Nebula, Abell 21: An old planetary nebula about 1,500 light-years away in Gemini. It is estimated to be over 4 light-years across. 

Sharpless 2-188: It found in the constellation Cassiopeia. It is about 9' in diameter and 2800 light years distant.

Soap Bubble Nebula: Located in the constellation of Cygnus, not far from the Crescent Nebula.

The Dumbbell Nebula, M27: The nebula is about 850 light-years away and 1.5 light-years across. It is located in Vulpecula.

The Owl Nebula, M97: One of the more complex planetary nebulae and it is located in the constellation Ursa Major. It is located approx. 2030 light years away and is about 8,000 years old.

M46: A rich open star cluster in the constellation Puppis. Within a diameter of 30 light-years at its distance of 5400 light years, it contains over 150 bright stars.

The Ear Nebula: A bipolar planetary nebula in the constellation of Cygnus. It is about 6' long.
