Elephant Trunk Nebula (IC 1396)

Post by Christopher K. » May 22nd, 2014, 10:01 pm

The Elephant Trunk Nebula is 2450 light-years away in the constellation Cepheus. The nebula lies 1˚24' SSW of the M-class, magnitude 4.2 star Erakis. I'm far from an expert at reading Burnham's abbreviations, but the summary reads something like "elongated, faint, extremely large nebulosity, 135' x 165', surrounds O-type double star Struve 2816".

The Elephant Trunk suprises some people as it is not too well-known yet has a brighter listed intrisic magnitude than the Orion Nebula. A picture of the Elephant Trunk from Eric Coles is slide number two in the collaborative gallery from Time Magazine and the Astronomical League.
