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.

Brilliant, once I got it going
Tuesday, 10 May 2022  | 

I bought this controller to replace the hand control unit for the Skywatcher electronic focuser, which I have attached to my Skywatcher Dobsonian.
The standard hand control unit that comes with the electronic focusser was pretty awful in my opinion, not well made, no off switch, very patchy quality, no mains option and the 9v battery was a pain to fit with very delicate wires.
So this RF controller seemed to solve all the problems.
Except at first it didnít. I could hear it hum so it was on, but no lights showing and not working. ďHere we go again with skywatcher electronicsĒ I thought.
Then I read the blog link in the product description and it describes sometimes doing a reset. So I opened the unit and before doing the reset found the daughter board wasnít properly pushed into the motherboard. A small wiggle and it started working. Itís now working like a dream, fine focus is excellent. Iíve used it 4 times on the moon so far for viewing and imaging and itís perfect.
Great service from FLO as ever, they offered to replace the unit immediately, but luckily didnít need to.
If you want to replace the focuser on your skywatcher classic dob to give you fine focus, this unit plus the motorised focuser is a great option. Or you could fit the manual 2 speed focuser from skywatcher.

Excellent upgrade for your focuser.

I recently fitted one of these remote controllers to my 200P and I am very impressed with its performance. Being able to use a 12volt supply it now runs at four different speeds which is a great improvement on the original slow to very slow controller. Well worth the modest price IMO.

It works

I've not had chance to try it at night yet, but it works as described with the SW focus motor. It has an ON/OFF switch so you shouldn't have to take the battery out between sessions, unlike the original, wired controller. So far, so good!

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.
Friday, 4 June 2021  | 

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.
