Lacerta Extra Low Profile Rack and Pinion Precision Dual-Speed Focuser 1.25" - 2" Compatible
Lacerta Extra Low Profile Rack and Pinion Bearing Type Precision Dual-Speed Focuser 1.25" - 2" Compatible
Guided on 8 bearings and a precision rack and pinion rail, it provides a 57mm minimum height that is one of the lowest profiles on the market. It is very good value as it is very similar in performance to those much more expensive professional grade focusers. It comes with a low profile (2mm) 2" to 1.25" adapters. Recommended for Skywatcher and similar Newtonian Telescopes.
A high quality dual-speed focuser designed as a direct replacement/upgrade for the rack & pinion focuser supplied with the Sky-Watcher 200mm & 250mm Newtonian Reflector Telescopes, but it might be also directly compatible with many other telescopes. Will accept both 1.25" and 2" standard format eyepieces. Features adjustable tension and locking clamp. It is a much more precise and heavy-duty focuser than a normal Crayford as it features 8 bearings that makes its movement much more precise, plus the drawtube moves by a rack and pinion drive system to further improve precision and especially payload. We've tried it: once secured with both thumbscrews, we were not able to move it by hand, although we applied quite a force...
As this focuser is a dual-speed version, if you install a motor focuser, it's easy to understand that you'll have to unlock the motor each time when you want to use it manually...
Min Height: 57mm
