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.

• This is an L-shaped bracket that attaches in four different places on the back of any of the CDK models.
• This is used to mount a finderscope or some other accessory.
• Two 1/4-20 screws provided attach the bracket to the backplate of the telescope and two 10-32 threaded holes spaced at 1.450″ can be used to mount accessories too.

Dovetail counterweight adapter.

Counterweight kit for CDK12.5 attaches to the dovetail bar for critical balance in Declination.

The EFA PC Port Kit allows connecting the PWI Software to the PC port on the EFA Box. Each kit contains:

• a USB to Serial Converter
• an Ethernet to 9-pin Adapter and
• a short Ethernet cable

The EFA (Electronic Focusing Accessory) control box can be mounted to the back plate of any PlaneWave telescope OTA (12.5 through 24 inches). The EFA Kit reads the primary mirror and ambient temperature sensors.The EFA controls the fan systems that are built into each telescope.

A Hand Controller is provided to control an optional Focuser or Rotator when standing at the eyepiece. The EFA kit comes with PlaneWave Interface (PWI4), a software package that controls all EFA functions from a PC. Cables and adapters are provided to attach the EFA kit to a PC. The EFA kit is ASCOM compatible.
