Skywatcher Auto Focuser.

I bought this to use with my new Skymax 150 and after making up a custom mount and fittings I have it working nicely.
Nice focuser for the Mak, good micro focus.

Not quite compatible with a duel speed focuser
Wednesday, 9 June 2021  | 

Got this to help focusing my skywatcher 200pds during astrophotography. Really easy to fit and works like a charm. However the 200pds is fitted with a duel speed focuser with the twin knob side the only removable ones. This means the motor bracket doesn't quite fit so can only be fitted on the last 2 screw holes, and only can be attached to the low speed. Not ideal but at least I can focus so slowly now I can get pin point accuracy.

Highly recommended

I bought this as I was having trouble focussing my Skywatcher 150P with my Nikon D5300 attached. The autofocuser offers very fine control with no vibration, and within minutes I had nice sharp, round stars in my viewfinder. Very easy to set up and install too. It's a game changer really.

Great focuser kit

Got this for my Williams Optics Megrez 72, which with a couple of threaded screw holes tapped into the base of the scope allowed the focus motor to sit nicely onto the telescope using the flexible coupler supplied

Affordable motor with speed adjustment
Thursday, 14 January 2021  | 

As a user of the SW Skymax 127 Mak I wanted to add an electric focus to improve my planetary imaging. SW don't provide a plug and play solution for this, and other vendors solutions are expensive. So I ordered this motor from FLO knowing I would have to buy some belts and gear wheels and make up a DIY attachment to fit the motor to the 127. FLO delivered the motor this week and I've put it all together and look forward to trying it out. The motor uses a PP3 9V battery and offers a useful speed adjustment. Operation is quiet. A good value product, just make sure you research attachment options if you want to use it on anything except a refractor.

Flimsy. Battery hard to fit.

I installed this on my Skywatcher Explorer 200. I fitted a camera and the motor was no longer able to move the focuser. 9 volts is not sufficient power to move it. I've dismantled and refurbished the focuser and refurbished the motor and gearbox but to no avail. It just doesn't seem to have the power required. I've not contacted FLO, as its been a weird time in history! I know they are very good though...!


It sounds like the motor is faulty, this is not normal - please get in touch.

Skywatcher Auto-focuser

Product received well packed within the terms of delivery. Put immediately to use on a 2-inch focuser via pulley and rubber band rather than flexible coupling provided to save dismantling focuser assembly. Ideal for planetary imaging with small focusing increments. Works through 10:1 reducer for minimum load.

Great service FLO as usual
Very easy to attach and set up on startravel scope.
In operation very smooth and allows for very easy focusing. This also has little or no apparent backlash and doesn't seem to slip at all
The kit contains more items than the instructions detail meaning it will fit quite a lot of telescopes.
Also means the silver adaptor (pre attached) has to come of first on the startravel scope and is difficult to see from instructions which way up the adaptor plate goes. Thank goodness for web videos
Note the connector is flexible so give no wobble to the system
All in all a brilliant product
