Lacerta LinearPower Precision Dual-Speed Focuser 1.25" - 2" Compatible
Lacerta CRnLP Precision Dual-Speed Focuser 1.25" - 2" Compatible.
Guided on 4 bearings and a rail, it makes this focuser one of the best value focusers as it is very similar in performance to those much more expensive professional grade focusers. It comes with a M54 thread and FUF543 eyepiece-holder
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. 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 4 bearings that makes its movement much more precise, plus the drawtube is secured into a rail system for 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...
As you can see from the pictures, this focuser is nothing like the usual focusers, the 4 bearings and rail give it a much more precise movement and very heavy-duty action to the whole structure. (2 bearings are visible on the image, the other 2 are inside the body of the focuser, invisible from this angle...)
