This adapter attaches to the back of the CDK17 or CDK20 using the same retaining ring that holds the PlaneWave 3.5″ Hedrick Focuser onto the telescope. With this adapter, you can mount an ultra low profile Clement Bellerphone II, 3″ Focuser.
Now, one person can easily balance a CDK on the L-Series mounts using the Ascend accessory! The Ascend can attach to either the front or rear of the #200919 Dovetail Clamp and precisely slide the CDK forward or back for accurate balance. Ascend uses a long pushrod to safely balance in the mount’s declination/altitude axis with the turn of a bolt.
The back plate on all of the CDK models has four mounting positions for a finder mounting plate.
The finder mounting plate attaches to the back plate of the telescope and the quick-release finder bracket attaches to the mounting plate.
If the telescope is used on a German Equatorial mount it may be convenient to purchase two finder scopes, one for the east and one for the west side of the telescope.
The finder scope is a Baader 10×60 Varios with mounting rings and L- bracket.
