About this product

Model:  moonlite_dc_motor_focus_bundle

Please ensure you choose the correct attachment bracket for your focuser from the 'MoonLite Motor Attachment Bracket' drop down.

Add super-fine focus ability to your MoonLite focuser with this DC motor focuser option. 

Uses a DC gear-head style motor with a very fine gear box providing extreme fine focus ability and strong torque. The motor assembly uses a slip clutch allowing both motor and manual operation of the focuser at the same time.

Connects to the hand controller with a 1/8" stereo 6 foot long cable. The Battery operated hand controller can vary speed from very slow to very fast in a pulse width modulated mode. The fine movement ability makes the focuser ideal for visual use or manual imaging use. The dual port design of the controller allows for control of a second focuser from one handset.

Slip Clutch

The Slip Clutch allows you to choose between manual or motorised operation of the focuser without the need to remove the motors.

The amount of slip can be adjusted on the new slip clutch by adjusting the tightness of the slip clutch ring. For manual knob operation of the focuser, turn the silver knurled ring loose. For motor operation of the focuser, tighten the silver knurled ring.

To adjust the knurled rings tension, it helps to hold the manual knob still with your right hand and turn the clutch ring with your left hand. Holding the manual knob in place will keep the shaft from turning allowing the clutch ring to tighten / loosen the clutch.

Note: No damage will be done if the focuser motor continues to run past the mechanical stops of the drawtube's travel. Even if the clutch is tight, it will simple slip when the travel runs out. 

Note: Designed for non-PC control of your focuser. For PC automated control please Moonlite's High Resolution Stepper Motor option.

Well worth the wait

The delivery date was extended due to production issues at the manufacturers (now resolved and no fault of FLO who kept me updated), but when it arrived, was easily fitted to scope and works brilliantly as I can now adjust focus whilst looking at screen, instead of running backwards and forwards between scope & computer.
