The Ghost of Cepheus, a reflection nebula in the constellation Cepheus. It can be located in sky charts as Sh2-136 or VdB 141. A reflection nebula is a cloud of dust which reflect the light of nearby stars. It is best to image the reflection nebulas with broadband filters (Optolong L-Pro, Astronomik UV/IR filter, Baader UV/IR filter), which allow a broad spectrum of light to pass.
