The usual rapid and efficient ordering and delivery service from FLO plus accurate technical advice that enabled me to make an informed decision about purchase. Bought this focuser to replace the high profile original on a Synscan 250 mm dobsonian. A real improvement over the original - smoother and less inclined to slip- allowed the telescope to reach focus with a camera- and overall very good value for money. It was easy to fit and no need to drill new holes. The only gripe was that the original focuser aperture in the side of the Synscan is of a wider diameter than is taken up by the replacement focuser meaning that light and dust can get in around the edges. Thus I cut and glued in place some foam to fill the gap which was quite easy to do and solved the problem.

I decided to get this focus to see if I could achieve the neccesary in focus on my Quattro to use the ASA 0.73x reducer, I didn't want to have to re-drill the tube or move the primary, so this was a try out to see if it could be done......it works!
I didn't have the screw hole issue that others had, I just placed the screws in first and then tightened up the nuts on the other end, but yes the screw holes are a bit awkward if your nuts are fixed to the tube. I think the focuser is better than the stock focuser that came with the quattro from a build perspective too. I am overjoyed that I can now image at F2.9 this season.

This is a good quality focuser for the price. My first impressions when I opened the box was the high quality finish with of sturdy metal base and pleasing appearance. The fine focussing knob worked a treat on my homemade Newtonian reflector compared to the old rack-and-pinion focuser it replaced.
The only downside I found was that two of the four boltholes were positioned very close to, and even partly underneath, the focusing barrel. I therefore found the fitting and tightening of the bolts rather awkward. It seems to me that this is a design fault and I see no reason why the manufacturer could not have placed the two holes at a slight distance from the barrel for easy tool access. Hence the reason for the 4 star rating.
Having said that, it is still worth every penny for it's high quality and excellent performance.

This is not the best focuser on the market but is very good for the price. Nice smooth action and good fine focussing. I would not recommend if you expect it to carry a lot of weight such as a filter wheel or DSLR camera but for observing is great. I replaced the stock single speed focuser on Skywatcher 8" Dobsonian and was a direct replacement, no need to adjust the holes in the tube. As I say there are better focusers but probably 2 to 3X the price as well so for observing more than adequate.

brought this a while ago and is 100%better than the standard rack and pinion i bought it for photo work with a dslr/webcam and focus is so much more easier and precise get one you will never look back
