  The Sculptor Galaxy (NGC 253)

  flickr.com - Martin Heigan

  My first wide field Galaxy photo, 6 months after getting my first Telescope (a small inexpensive GSO 6" Newtonian Reflector) . Ancient light from a Galaxy far, far away (situated 11.42 million light years from Earth). The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy (NGC 253), is an intermediate spiral galaxy in the constellation Sculptor. It is a Starburst galaxy, which means that it is undergoing a period of intense star formation (well it was 11.42 million years ago, as the light took that long to reach us). Recent research suggests the presence in the centre of this Galaxy of a Supermassive Black Hole, with a mass estimated to be 5 million times that of our Sun. Photographed at the West Rand Astronomy Club's Annual Star Party at Mountain Sanctuary Park (North-West Province, South Africa). A special thank you to Neil Viljoen from "The Telescope Shop" for his assistance.
