William Optics Eztouch Mounting on EQ6 Tripod

William Optics Eztouch Altazimuth head on Skywatcher EQ6 Tripod.

Makes a very sturdy combination and is excellent value.

This new improved head mount is made by William Optics.
It is entirely aluminum made, with a stylish sanded finish and laser engraving. The knobs are stainless steel. We named it EAZY-Touch because it's easy to set-up, and it is easy to use. Tracking stars even at high-power has never been easier. The extremely high quality allows for smooth movements without the need for any slow-motion controls. This very solid Alt-Az Mount is fitted with a Vixen bar clamp on one side and can mount Losmandy-style plates on the other, allowing you to mount to telescopes at one time. Mounting two telescopes should allow you to balance each other more easily too. Two scopes, twice the fun: invite your family to observe with you, or use a larger and a smaller scopes at the same time parallel-mounted.

The head weighs 3.5 kg and mounted on a quality tripod will offer all the stability you need without compromising its portability and ease of use. The "Teflon inside" guarantees that there is no backlash and that your mount will peform oustandingly.
