A Very High Quality Focuser
Tuesday, 5 July 2022  | 

I purchased this focuser to replace the stock synta on a Celestron 102mm F6.5 SLT. It fit perfectly and is a VERY significant upgrade. Essentially it takes a $300 Cdn telescope and makes it feel like a $1000 one.

The package arrived in Canada in a week. The focuser install couldnít have been easier. I removed the three retaining bolts on the stock focuser and gently inserted the new one. It was a tight fit but after snugging it in I gently tapped the new focuser in on a table making sure the screw holes maintained their position. It literally took 10 minutes. I then put the finder shoe on using the supplied screws and was good to go!

Service and communication from First Light Optics was top notch and both the staff and myself thought it would probably fit - and obviously it did.

This is my first purchase from FLO as Canadian stores donít seem to supply this part. I would use FLO again in a second if the item is not available in Canada.

In short, a great product with good service - Highly Recommended.

Clear skies all!

Great upgrade and product quality
Tuesday, 24 May 2022  | 

First >> parcel was delivred really fast. From UK to Canada took 3days with DHL.

Bought The focuser to replace the original on from my Skywatcher 120/600. With the original; I was never able to align it with the center of the optic and I had some tilt issues.
The new product is heavy compare to the original one but not that much. My camera is now perfectly align with the center of the glass and the focus is relly cool. Durring my last test was during a foggy night and i was able to get a focus value of 2.3. Compare to my previoius 4 arround during clear sky, it is a great improvement. I waiting for more clear nights.

The mount was easy except the skywatcher 's paint was thick. I use some sand paper to remove it and then >>> perfect.

The wheels are really smooth and pleasant to use.
I mounted my ZWO Auto Focuser on it and no problem.

Finally, my first impressions and tests are really good and i think i will enjoy it and I can recommand the product.

Also, Thanks for the support service to quicly replied my questions before my order.

The stock focuser on my SkyWatcher 120ST was terrible, so I replaced it with this focuser. Installation was easy, just ďplug and playĒ. Highly recommended!!

2Ē Dual speed Crayford focuser
Wednesday, 20 April 2022  | 

An excellent upgrade from the existing focuser that was supplied with the scope. Very nice finish on the black machined metalwork. The action is silky smooth throughout the full range of motion. I had to remove the fitting (adapter) on the telescope to sand the thick layer of paint away so that the focuser would slide into position. Once fitted i removed the two grub screws to expose the threaded holes for the finder shoe. Very pleased with this purchase. Top class service from FLO as usual

Fitting to a Celestron 102.
Thursday, 7 April 2022  | 

After some sage advice from Chris at FLO, I took a safe bet on the fact that the Skywatcher unit would also fit the Celestron 102 Omni. I won the bet it seems and the unit fitted ok although, with my example needed a bit of light sanding to the inside of the tube, to ensure a non forced fit!
The machining and finish of this unit is superb and light years ahead of the standard 2" unit on my Celestron. Also, the new unit is a dream to use, so precise and smooth, it's really changed the whole scope. For a 160 pound outlay, I think it's a bargain!
FLO service was top notch, I ordered on a Wed am, it was dispatched that same day and arrived via DHL here in Turks And Caicos Islands on the Friday afternoon....amazing!

Finely tuned machine!
Wednesday, 23 February 2022  | 

Purchased to replace a standard "single" speed focusser on a Skywatcher 120 achromat. The new dual speed Crayford was quick and easy to fit - no problems at all! It performs very well, and the fine tuning ratio is perfect. It substantially reduces handshake when compared to the old standard single focusser. Good investment and recommended highly.

Really nice quality for the price
Wednesday, 16 February 2022  | 

I wanted to replace the original focuser on my ED80 and have been looking around for a replacement. Precious few options in the second hand market at the moment, so I plumped to look for a new one and came upon this, finding one that FLO had reduced a bit because of an open box or something similar. The reviews were good and so was the price and this certainly seems the best value focuser available (and even better with the price reduction!) Very well packaged by FLO and delivered in the expected fast timeframe. The item itself is much better quality than the original and moves extremely smoothly. Fitting was very easy and I had no problems with tight fit as described by some reviewers, in fact the fit was perfect, allowing for easy installation, but not allowing any rattle or movement when in place. Unfortunately the Great British weather has limited my testing so far, but I am extremely happy with the purchase.

Fantastic value for money
Tuesday, 28 December 2021  | 

I bought this to replace the stock rack and pinion on my Sky-Watcher Evostar 120/1000 achromat. It arrived in Australia on Christmas Eve. Thanks for the Christmas present, FLO! It's a beautifully machined piece of gear and, after a little tweaking, works flawlessly. As others have stated, the paint had to be ground off on the interior diameter of the collar. After that, the new focuser slipped in easily. The 'tweak' I mentioned involved solving a grinding sound. With the help of an old 2015 message on Cloudy Nights, turns out the knob on the left (the coarse knob) was hitting against the body. Just releasing the grub screw and sliding the rod along a fraction solved the problem. Handles a DSLR and a massive Explore Scientific 30mm 82 degree eyepiece + WO 2" dielectric diagonal with no problems of slippage whatsoever! I would definitely recommend this to anyone looking to upgrade their basic focuser.

Silky-smooth
Thursday, 25 November 2021  | 

I bought this as a "straight out of the box" upgrade for a Skywatcher Startravel 120T (OTA) and FLO very kindly fitted it for me before dispatching the scope. Because it was fitted, from new I have no means of comparing it to the standard item which normally comes with the scope. But (and this is a BIG BUT!) having had universally disappointing experiences with three previous (standard) skywatcher focusers which came with their respective scopes I had no intention of being disappointed for a 4th time! My experiences with Skywatcher standard focus assemblies is that they are rather slack and sloppy (too much backlash, and prone to move out of focus when any degree of friction is applied to the focuser to compensate). The upshot of which is that you can spend far too much time frustratedly fiddling with the focus and far to little time looking at your intended celestial objects.
Well, this upgraded focuser is a revelation. It is ultra smooth and slick, totally free of any backlash, stays exactly where it's set and transforms an otherwise perfectly workman-like scope into an instrument which is a joy to use.
It might seem expensive at almost £160.00 but I can say that it's transformative effect is worth every penny spent.
