FocusRF - Remote Control for DC Focus Motors

This product is designed to directly replace the handset in the Skywatcher Autofocuser kit.

It allows you to focus the telescope remotely from up to 20m away, without any trailing wires that will always wobble the telescope a little while you are trying to focus.

Extremely simple operation with 8 buttons arranged in 4 rows of 2. All the left buttons turn the focus one way and all the right buttons turn it the other way. The buttons at the top are slowest, down to the fastest ones at the bottom.

The FocusRF is microprocessor controlled and can be configured to use multiple remote units, and you can even adjust the minimum speed that it reaches (this will depend on your power supply or battery, as well as the actual motor you are using).

Power can be provided from a 9V PP3 battery (not included), or an external supply (not provided) which should be between 7V and 13V, 2.1mm tip DC Jack with centre positive.

 See the 4tronix blog for details of configuration etc.

4tronix FocusRF - Remote Control for DC Focus Motors
Wednesday, 8 September 2021  | 

Bought to replace the curly wurly cable and hand controller as I run the scope from a warm room, and having the cable (well 2 long ones joined by a connector) draped over the observatory floor in the dark was a pain. This is a great solution - the hand remote is a bit small but works fine, and no more cables to trip over.

Fantastic piece of kit.

4tronix FocusRF - Remote Control for DC Focus Motors is a really fantastic piece of kit, worked straight out of the box. I am using with mains power with an adapter instead of battery however. I adjusted the speed controller as my focuser on the bresser 100mm refractor needs a little more torque. Highly recommended for the price.
