New! Superbly engineered dual-speed Crayford focuser for Newtonian reflectors! Designed to fit tube assemblies over 7" external diameter.

This new Antares focuser is the ideal upgrade for single speed basic crayford focussor fitted to the BC&F Revelation and Meade LightBridge Dobsonian telescopes and is a perfect and easy to fit replacement for the existing focuser.

The Antares dual-speed Crayford focuser features a focus control with 1:1 and 10:1 speed ratios allowing superbly smooth and precise focusing at all magnifications. The focuser attaches to the telescope tube via four fastening holes positioned in each corner of the mounting pedestal.

The overall length of the focuser (minus the 1.25" to 2" eyepiece adaptor), measuring from the edge of the mounting flange is 72mm. Racked out the total focuser tube extension(again minus the eyepiece adaptor) is 107mm. The mounting pedestal measures 90 x 90mm and is 15mm deep at it's thickest point.

The focuser is fully (360 degrees)rotatable when fitted to the telescope.

The focuser has adjustable tension and stiffness making it ideal for carrying heavier eyepieces and cameras. And a great feature allows the focus point to be locked by actually disengaging the focus control knob by simply tweaking a thumb knob.

This is a beautifully engineered focuser and it functions every bit as well as it looks! There is absolutely no backlash and the adjustment can be super light-touch or stiff as you need it - but always with an ultra smooth feel.
