Excellent addition to my setup
Tuesday, 7 July 2020  | 

Purchased this to fit my Skywatcher Evostar 80ED. It works seamlessly with my ZWO ASIAir Pro - can highly recommend. This is a massive improvement and glad I made the purchase. I had a few problems attaching it to the focuser, but FLO helped me out and provided prompt and first class service as always. I ended up attaching this to the left and right screw holes (next to the centre tension screw hole) using M3 15mm bolts - be careful not to put too much tension on the focus tube though. I am truly impressed with the after sales service that FLO provide.

Easy to fit

Have attached to my William Optics ZenithStar 73. Fittings needed were included in the standard pack and were simple to apply. Hand controller worked without a hitch and temperature sensor works fine too. Will be configuring and controlling this using the excellent N.I.N.A software suite.

Got it to fit my Explore Scientific 80mm triplet. Needs longer bolts (Try M4 20mm or 25mm with washers) Massive improvement over manual focusing.

Excellent kit
Tuesday, 7 April 2020  | 

I only docked a star because none of the included screws fit my 130PDS focuser and I had to buy more. Other than that it wasn't much fuss to fit and it works a treat. I use it with APT and focusing is now a breeze.

ZWO EAF - Brilliant
Friday, 6 March 2020  | 

Compatible with lots of different focusers, easy to install on the ED72 and a GSO SCT (my testing so far) with many attachment options included. extremely good fine control, tested with Nina and Ascom. So good I bought a 2nd one.

Great experience
Tuesday, 4 February 2020  | 

I bought this along with some other equipment after an online discussion with FLO. They responded very quickly and efficiently to my questions and once this (along with three other items) was ordered it arrived very quickly and was packaged very securely. Would recommend FLO with no problem

Works well

Seems to work well with SGP and my WO73. It consistently produces excellent focus and fitting was easy. I will be adding them to my other OTA's in time.

Nice little focuser easy to attach to the scope and easy to operate via the ASiair controller. If you want to automate your system then this is ideal. Thanks FLO for a speedy delivery.

Bought this back in July, fitted with no problem to a William Optics GT71.
Works perfectly well and was the ideal solution to focusing for me.
