The Delta T controller is an optional accessory for dew prevention on CDK14 through CDK24 OTAs and the CDK700 system.
CDK12.5 to CDK24 and CDK700 telescopes come with primary and secondary mirror dew heating pads (CDK700 adds tertiary mirror heating), which are ready to accept the Delta T controller.
Controlled via PWI3 software for CDK12.5 through CDK24 OTAs (PWI2 for the CDK700).
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.
