Description

Stunning emission nebula IC 1396 mixes glowing cosmic gas and dark dust clouds in the high and far off constellation of Cepheus. Energized by the bright, bluish central star seen here, this star forming region sprawls across hundreds of light-years spanning over three degrees on the sky while nearly 3,000 light years from planet Earth. Among the intriguing dark shapes within IC 1396, the winding Elephant's Trunk nebula lies just right of the center. 12 hours of exposure through RGB and SII,Ha,OIII filters Mahon obsevatory(Thessaloniki),9MAO observatory(Ano Milia Pieria).

Description

The Rosette Nebula (NGC 2237, Caldwell 49, Sh2-275) is a large HII star-forming region that lies just east of Orion in the constellation Monoceros. This large molecular cloud is comprised of several smaller parts which were discovered by three different astronomers: John Herschel (NGC 2239), Albert Marth (NGC 2238) and Lewis Swift (NGC 2237 & 2246). In 1690, John Flamsteed discovered the Rosette's central open cluster, NGC 2244. From Earth, the nebula is approximately 5000 light years distant and appears to be about 1 degree across - roughly 5 times the size of the full Moon. At an apparent magnitude of 9.0, the nebula is impossible to see with the unaided eye making it's discovery difficult.
