#19842-12.5 Planewave 12.5" to OPTEC-4300

Description Compatibility Specifications The #19842-12.5 adapter fits beneath the Planewave pinch-plate on the 12.5-inch CDK telescope. 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.
