Initially disappointing but now resolved
10 March 2024  | 

I bought this recently along with the Tak bracket for my Espirit 100 and it was delivered promptly by Flo as usual. I watched loads of videos on how to install the product and thought it would be a straight forward process. However, when installing I noticed that the spindles (none of them fit properly) would bind my focusser at certain points. I was frustrated for most of the day and by that evening I had given up and was thinking of returning the item.
The next day I thought, let me try installing it on my other scope (WO Z61). This took all of 10 minutes to do and it worked perfectly straight away. My first imaging run with the focusser installed was seamless and the auto focus routine was bang on, so I'm highly impressed.
I'd offer a word of caution if you're thinking of getting this for an espirit 100ed. Maybe I was doing something wrong with the installation but I got a Pegasus focuscube v3 a couple of days later and installed that on the espirit without a hitch within minutes.
Overall, if you're sure this will fit your scope I'd highly recommend it!

Well made and easy to fit
18 February 2024  | 

Arrived next day as usual perfect service from flo and well packed, Canít wait to use it when finally the sky's clear. Motor seems well made and if good quality all parts seem well made and was very easy to fit to my new scope. Will definitely be adding more to my other scopes for imaging. Plugged straight into asi airrecognises it and manually moved it in and out to test the movement and was perfectly smooth.

Absolutely essential

This is the second EAF Iíve had and both provide great service for automated focussing for remote use. Thanks to FLO for great service as usual.

Well made focuser that is easy to fit with the optional C8/9 bracket
28 December 2023  | 

This is a well made focuser that is controlled by the ASI AIR software or optional hand controller. Attaching it to the bracket is a little fiddly but sturdy when all bolted down.
Need to keep the existing focuser bronze coloured ring in place to stop the internals from falling out if pulled!

EAF
06 December 2023  | 

Purchased this back in July to fit onto my Starfield 102 and it was easy to install.
Unfortunately after installing the EAF I found it to be faulty (the motor didn't operate), so after contacting FLO and running a few tests, they agreed to send out a replacement which worked first time, and has ever since. This unit makes focusing an absolute breeze, so easy to use and ensures you can remain in focus without ever stepping outside; I control it from indoors using NINA on a laptop. Top service from FLO as always, and only knocked off a star for the initial faulty unit (not FLO's fault).

ZWO EAF
02 November 2023  | 

Excellent service again from FLO. Order was placed at 2pm arrived next day at 2pm. Packaged extremely well also. This is my second EAF which is to be used on my SW 130pds also purched from FLO last year. The EAF is a must needed tool and just couldn't resist buying the additional one. Keep up the great service all at FLO.

Very Easy Installation & Setup
17 October 2023  | 

Had considered buying an EAF to compliment my ASI Air Pro & ASI 585mc camera but was hesitant to take the plunge and each time I convinced myself to get one it went out of stock. Finally bought it and fitted it to my 130pds Newtonian which was a very easy task with supplied brackets & adapters. I did a rough focus on a distant object in the daylight using the manual arrow controls. Almost 4 weeks of cloudy nights delayed my first light with it but the autofocus calibration routine ran flawlessly & my first v-curve appeared. So simple to use and nice tight round stars are very easy to achieve. Will definitely be getting another one for my refractor. As most of the reviews state I donít know how I managed without it !!!. 5 star service as ever from the people at FLO.

Fitting
29 July 2023  | 

I was unsure of the fitting and asked FLO for assistance - they went the extra mile Thank you Chris.
Chris even went to the extent of taking a focuser which looked identical to mine and taking it apart to ensure that I was using bolts in sockets which would not adversely affect the mechanism.
All fitted and working well. Now if only those clouds would go away !!!
