Monorail 2" Refractor focuser - more precise than a standard Crayford system
... advancement of the Crayford focusers, 96mm flange diameter

Monorail Okularauszug für Skywatcher Refraktoren

Our aim was offering a focuser for high loads and also high focusing precision like for heavy CCD cameras. Now we can present the TS monorail focuser.

The Monorail R86 fits to many refractors by Skywatcher, Orion and Celestron:
Enhance your refractor's mechanical quality with a first-class focuser. No complicated adaption work is necessary. The Monorail R96 fits e.g. to:
-- all Skywatcher, Orion US and Celestron refractors with 102mm outer tube diameter

Advantages of the TS Monorail focuser:
-- Higher load rating than normal Crayford focusers. Instead of small ball bearings, a massive stainless steel rail is used.
-- Precise guiding of the drawtube, no shifting when the locking screw is tightened.
-- Smooth travel and fine focus adjustments even under high load
-- Dual speed with 1:10 Mikro transmission for precise focusing
-- 360° rotatable

This is how the TS Monorail focuser works:

Monorail System

The function of the Crayford's ball bearings is take over by a massive stainless steel rail that is fixed to the drawtube. Nothing can be bended any more. Lateral guiding is performed by ball bearings who only have to do this function - they don't have to deal with pressure loads.

Guidance and centering of the rail takes place over its full length of approx. 40mm thus also prevents from bending.

With the small knurled screw between the focus wheels (on the lower side of the focuser), the tension can be adjusted.

The locking task is also solved better. The big locking screw presses exactly in the middle between the bearing points. No bending or shifting is possible, the load is distributed evenly across the full length of the rail.

"Well made focuser, smoothly working mechanics. Fits the 96mm diameter focuser side of my telescope well, assembly with the scope was easy. Recommended product."
