#19842 - Planewave to OPTEC-4300 Adapter

The #19842 adapter fits beneath the Planewave pinch-plate on the 14-inch and large CDK telescopes.  This adapter allows attachment of Optec's Gemini Focusing Rotator or TCF-Lynx3 Gen2 3-inch focuser.

Special Note:  for the very lowest profile mounting of the Gemini, Optec recommends replacing the socket cap screws holding Planewave's pinch-plate in place with flat-head screws.  This requires countersinking the holes on the pinch-plate.  Contact Optec Support for details.
