The AstroScope 9350EOS-FF module is a night vision attachment for several fullframe based EOS cameras which includes the EOS-1Ds Mark III and the EOS 5D Mark II.
The module sits between the camera body and SLR lens and provides night vision to the EOS line of cameras. The AstroScope doesn't interfere with optical image stabilization and it also passes through all electrical connections to the lens.
The module is capable of transforming darkened scenes in to brighter higher resolution screens and they also have a variable gain control so it can be easily adapted to various lighting conditions.
