The Revelation Superfocus 2-inch SCT Rack and Pinion Focuser is a recent development in the field of advanced focusers. An attractive 2-inch, high gloss-finished CNC-machined aluminium design that takes design advantages from the Crayford type of focuser: luxurious smoothness and precise focus transition – and combines them to the traditional strengths of the Rack and Pinion approach: loading capacity and durability. In the Revelation SCT Rack n Pinion bearing type Focuser, a thoughtfully designed focuser that ticks all the boxes. With a loading capacity of 3kg (considerably greater than a traditional Crayford), the Amateur Astronomer need no longer worry about the ability to securely support a large optical or Astrophotographic train on the rear of their telescope – load your system up with filter wheels, cameras, off-axis guiders and more without cause for concern.
The Revelation SCT Rack n Pinion Focuser has an integral central threaded locking system (engaged by an all-metal knurled locking knob, located on the underside of the focuser) that clamps a central channel that runs between the focusing rack, meaning that there is no compression of the focusing tube or the rack and pinion arrangement itself. This is easily the most secure locking system of its kind we have ever tested – much superior to other friction-based locks. With 30mm of focus travel and an incredibly smooth 1:11 dual speed focusing wheel arrangement, this focuser will be a great addition to any standard Schmidt-Cassegrain or ACF telescope. It will thread on to the rear cell of any suitable instrument (Meade, Celestron and more), in place of a traditional eyepiece holder/visual back and comes with a 2-inch to 1.25-inch step-down adapter with 1.25-inch dust cap) to ensure maximum compatibility with all your eyepieces and accessories and protection against dust, moisture or other ingress when not in use.
