Antares Dual Speed Crayford Focuser For Newtonians: £307.39

Comes complete with the JMI motofocus unit

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 focussors and is a perfect and easy to fit replacement for the existing focuser.

Hole spacings are 55 x 93mm with a 22mm central cutout for center fixings. Outer measurement of the drawtube is 60mm.

1.25" split compression and 2" brass compression ringed so it will not damage your eyepiece/camera barrel.It is also filter threaded for 2" filters when using 1.25" eyepieces.

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 profile of this focuser is 60mm from 1.25" fitting to base. 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.

The JMI motofocus unit motorizes the 10:1 microfocus knob for precise focus without touching the focuser. By not touching the focuser, vibration is virtually eliminated. For astrophotography, this motorized focus is a must!
