Owners of Zeiss Diascopes can attach standard 1.25″ telescope eyepieces to the scope with the use of a Baader Diascope bayonet 31.7mm (1.25″) ocular adapter. (see image right)
To use, simply insert a 1.25″ eyepiece in to the adapter, and secure with the 3 small screws. An allen key is included.
You will notice a groove around the Baader adapter. Take the larger of the rubber O-rings (included) and set in place. This will help give a secure fit when attached to the spotting scope body.
To connect the adapter to the Zeiss Diascope body, line up the mark on the adapter with the corresponding mark on the spotting scope and twist in to place.
A 2″ version of the Baader adapter is also available
