The Witch Head Nebula (IC 2118) - a photo on Flickriver

IC 2118 (also known as Witch Head Nebula), is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in Orion. IC 2118 lies in the Eridanus constellation, about 900 light-years from Earth.

Note: Galaxy (NGC 1752) - tagged in the mid-top region.

About the image:
This is one of the "1st Light" Deep Sky Objects imaged with my William Optics Star 71mm f/4.9 Imaging APO Refractor. It was photographed on a very warm Summer's evening, which always makes the signal-to-noise ratio an interesting challenge during processing.

Location:
The rural dark skies of the African Bushveld in the Waterberg, Limpopo Province, South Africa.
