Hedrick Focuser 3.5" for PlaneWave CDK 14–17–20–24

Description:
The Hedrick Focuser 3.5" by PlaneWave is a high-end focusing unit designed for CDK 14", 17", 20", and 24" telescopes. Precision-machined from black anodized aluminum, it employs a worm-drive mechanism supported by five guide bearings, ensuring excellent rigidity and slip-free operation. The focuser offers a 33 mm linear travel, enabling accurate focus even with complex optical setups.

An integrated stepper motor allows remote operation through the EFA (Electronic Focuser Accessory) module or via PlaneWave Interface 3 (PWI3) software on a PC. This full automation capability is ideal for robotic or remote observatories. The rigid mechanical structure ensures perfect repeatability, essential for advanced astrophotography.

The focuser mounts via a standard 3.5" thread and supports imaging setups up to 9.1 kg, including CCD cameras, filter wheels, off-axis guiders, or correctors. With no slip or backlash, the focus remains stable throughout long exposures. Its seamless integration into the PlaneWave ecosystem guarantees reliability and optimal performance in demanding professional environments.
