The lightweight Electronic Focusing System (EFS) with HSM30 Motor, control box, and hand controller is a convenient stepper controller that works with allASCOM compliant software.

Control box is 4.13-inches (105 mm) long, 2.87-inches (73 mm) wide and 1.1-inches (28 mm) thick.

Hand controller has an innovative feature in that you can change the number of steps the focuser moves from 1 step, 10 step, or 100 step increments. This is done by pressing the knob on the hand controller. Each step speed has an LED light mode, RED 1 step, Amber 10 step, 100 Green step. It is connected to the EFS control hub via RJ11 cable.

The EFS system draws a maximum 1 amp of power at 12V

The EFS can be controlled by standard USB cable

HSM30 Stepper Motor

This “Handy” stepper motor unit works exclusively on the Focuser Boss II electronic focuser. The design of this motor housing allows you to still be able to manually turn the focus knob on the focuser by simply turning the over-ride knob on the motor housing.

• The HSM20 has 19,450 steps per inch and the HSM30/35 has 24,300 steps per inch.
• The HSM20 motor unit fits the 2.0-inch FeatherTouch focusers, MPA Retrofits (Takahashi and Tele Vue), and Micro FeatherTouch Telescope Focusers for the SCT scopes.
