Description

North America & Pelican nebula
The North America nebula and its surrounding nebulae are located in the constellation Cygnus. It basically is one giant emission nebula with many smaller dark nebulae dividing it. The North America nebula with the catalogue designation NGC 7000 and the Pelican nebula with the catalogue designation IC 5070 are two of the most popular nebulae for astrophotographers. These nebulae can be seen from the northern hemisphere in summer and early fall high in the sky close to the zenith. The nebulae are both about 2'950 light years away from the solar system.

Sadr Region / Butterfly nebula
The Butterfly Nebula is located in the constellation Cygnus and is mainly an emission nebula. However, there is also a smaller dark nebula (LDN 889) directly in the centre of this red nebula. The emission nebula has the catalogue designation IC1318 and is sometimes called the Gamma Cygni Nebula. Gamma Cygni is the bright star directly above the Butterfly Nebula. Gamma Cygni or Sadr is a special F8 type star. It is special because unlike most other supergiant stars it is neither cold and red nor blue and hot. It is much more yellow and about as hot as our sun. Sadr is about 1,800 light years away from our solar system. The nebula itself is estimated to be between 2,000 and 5,000 light years from Earth.
