Great replacement focuser for ED80
Monday, 25 May 2020  | 

The focuser is excellent build quality with smooth action and fitted straight in to ED80 by simply removing three small screws from scope. Screw holes in this focused aligned precisely. My only gripe is that I had wanted to fit my Sesto Senso autofocuser unit in place of the knurled focused knobs but the grub screw on the microfocuser knob fits none of my Allen keys that I use on other focusers aon other scopes...seems to be somewhere between 0.5mm and 1mm.

Much better than expected
Friday, 8 May 2020  | 

Have a Sky-Watcher Evostar 120 and as have seen in comments else where the focuser could be better, often had difficulty to get a sharp focus for reasons discussed in reviews here.
after a lot of looking there may be better focusers but for the money this what could justify for the telescope.
only issue was the fitting the focuser. when removed the old one i needed to remove a little paint inisde the tube to allow the new one to fit, probably bye bye waranty .
but the difference .. its so smooth to focus now, the rotation of the focuser so that dont have to release the diagonal to reposition eyepiece (is wonderfu) and best of old the attachment of the diagonal to the focuser is solid, no movement unlike the R and P focuser that came with telescope, when i was afraid the eyepice could fall out due to the poor cpnnection on the diagonal.

is like a new telescope !!!!

Support from FLO team was quick and helpful

thank you

Replacement focuser
Wednesday, 18 March 2020  | 

I looked at the other focusers out there - Moonlight, Baader etc - and although they are premium quality units, I just couldnít justify the money for what is just a bit of a nice hobby for me. So, I bought this one to go on my Skywatcher 80ED, and quite honestly itís brilliant!!

Undo 3 screws on the old unit and remove, slot this one in, put 3 screws back in - job done literally took 5 minutes. Perfect fit and alignment with the tube.

Really smooth action - the original SW had a constant sticking spot, despite following all the Ďtuningí tutorials. The focal markings on the top mean that I can always get straight back to 99% focused, if the tube gets moved or pushed in. Then just a tweak with the fine knob.

Well worth the money to get rid of the SW unit.

A vast improvement over the standard one!
Monday, 9 March 2020  | 

Vey well made, for me, the most impressive feature which I hadnít even realised it did, was the fact that it rotates too! The standard one didnít! The benefit of this is that when your mount has rotated 180 degrees your eyepiece can be rotated back up to the vertical without having to adjust everything! Itís just one locknut to loosen. Itís worth having just for that! I canít believe this isnít made more of in its feature list! Of course the actual job of focusing is also superb.

A Class Act

I bought this to replace the helical focuser supplied with my Skywatcher StarTravel 102 that I use for solar observation. The dual speed focuser is very well made and extremely smooth in operation. It and its finder shoe accessory was straightforward to fit. Recommended

Significant upgrade for StarTravel 102
Saturday, 7 September 2019  | 

The difference between the stock focuser and this unit is like night and day! This unit is so smooth to focus with and the fine adjustment really brings things into sharp focus with ease. A couple of notes based on what I have seen in other reviews compared with my own experience. The focuser is a reasonably tight fit and required a bit of a wiggle to settle into place, but once in place it's a nice snug fit. I can confirm the focuser now has two mounting holes for the Sky-Watcher Finder Shoe, these are covered by two grub screws that can be removed to allow you to fit the shoe. Astonishing next day delivery from FLO! Will be back for more equipment later!

Crayford focuser
Friday, 8 February 2019  | 

This is a great Upgrade for old eyes , With the original focuser i felt i wasn't able to Focus a 100% , but With the fine adjustment on this New one , i am.
i just got it fitted a couple of days ago , and had it tested last night.

I dont think you can go wrong with this one.


Geir asked us to add that the scope used was a Sky-Watcher Startravel 120.
