• The Series-5 focuser is a large capacity focuser for use with Alt/Az, or equatorially mounted systems.
• The focuser is capable of lifting 40 lbs (18 kg) with a travel range of  0.6-inches (15,200 microns).
• The Series-5 focuser can be stacked with the Series-5 rotator for a complete focusing rotator solution (combined 2.78″ of occupied backfocus).
• Occupies only 1.675” of backfocus.
• 464.4283 encoder counts per micron
• Controlled via PWI4 software for autofocusing and optional field de-rotation (if using an Alt/Az mounted system).
• Requires the Series-5 Controller.
• Compatible with the DeltaRho 350 and RC700 telescopes.

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.

• Feathertouch 2″ Diameter Dual Speed Focuser with 2.5″ of Travel.
• Great choice for refractors and Ritchey Chretien and CDK telescopes.
• It is precision engineered to deliver smooth operation and no image shift.

• The IRF90 is a large capacity Integrated Focuser and Rotator for use with Alt/Az, or equatorially mounted systems.
• Occupies 3.5″ of backfocus with the focuser fully racked in, and 4.7″ when fully racked out.
• The Focuser is capable of lifting 40 lbs (18 kg) with a range of 30mm (30000 microns/1.2″).
• The Rotator has a 90mm aperture with a range of 365 degrees with hard stops to eliminate any chance of cord wrap.
• IRF90 is controlled via PWI4 software for autofocusing and optional field de-rotation (if using an Alt/Az mounted system).

• The Hedrick focuser designed by PlaneWave is a heavy duty no-slip focuser capable of handling an imaging payload of up to 20lbs.
• Occupies 3″ of backfocus with the focuser fully racked in, and 4.2″ when fully racked out.
• Focuser travel range of 30mm (30000 microns/1.2″)
• The focus tube runs on 5 bearings and is driven by a leadscrew so there is no chance of slipping.
• Focus may be automated through a computer using PlaneWave’s EFA Kit and PWI3 software.
• The focuser comes with pre-installed motor that can be controlled with the EFA hand controller or PWI3 software.
