Description

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.

Julian R. ★★★★★

Finally, a solid adapter that lets me mount my Gemini focuser directly onto the CDK without any wobble. The threading is precise and mates perfectly with the pinch-plate, so I didn’t have to chase collimation all night.

Kevin ★★★★★

The threads on this adapter are cut perfectly—no wobble when I attached my focuser to the CDK. Finally, that gap between the pinch-plate and the rotator is bridged.

Jacob N. ★★★★★

Had to swap my Optec gear onto the Planewave CDK, and this adapter dropped right into the pinch-plate recess with zero fuss—the machining is spot-on. Now the Gemini focusing rotator sits solid, no wobble at all.
