| Object | IC2118, "Witch Head Nebula" |
|---|---|
| Description | The Witch Head Nebula is a large reflection nebula near Rigel in the constellation Orion. It was captured here with a telephoto lens at a focal length of 200mm. My red subexposures were unfortunately out-of-focus causing red rings around most stars. |
