Type: Reflection Nebula
Constellation: Eridanus
Distance from Earth: 900 light-years
About: IC 2118, commonly referred to as the Witch Head Nebula because of its distinctive shape, is a large yet very faint reflection nebula. It is thought to be either an ancient supernova remnant or a gas cloud that is being illuminated by the nearby supergiant star Rigel. Located in the Eridanus Constellation, it is approximately 900 light-years from Earth.
This is the first astrophotography image taken in the backyard of my new home in Mansfield, Georgia. In my former home in Illinois, I was unable to capture this target as I was at 42° North and this never reached over 20 degrees. The light pollution would have made it difficult as the skies are approaching Bortle 6. However, my new home is at 33° North, allowing me to image the target at 48 degrees, making it much easier to view.
