Nikon Coolpix 990 Afocal Coupling Assembly

Afocal Coupling Nikon Coolpix 990 Digital Camera to a telescope

In afocal coupling the Nikon Coolpix 990 is aimed into the telescope eyepiece. Aiming the camera can be by hand holding the camera, mounting the camera on a tripod next to the telescope eyepiece, building or buying an adapter to hold the camera over the eyepiece or using an universal camera adapter to attach to the camera lens.

A benefit of the Nikon Coolpix 990 is that it has 28mm lens threads mounted on the camera body. Using a 28mm to T-mount adapter the Nikon Coolpix can be mounted to a standard universal camera adapter.
