I'm using Celestron's AVX 6" refractor. It uses the rack-and-pinion focuser and I felt pain when I focus a faint object for severe shaking.
This focuser is very easy to install and intuitive to use. Of course there's no Power-On switch, and.. a little bit slow, It's sufficient to use who do not want to buy very expensive and more accurate step motor guided focuser. (I think this focuser may use a simple geared motor :) ).
I just used the Duracell's FC-1 battery, but next time when I exchange battery I'm planning to use FC-1 typed Li-ion battery for more powerful work. (Frankly speaking, I don't know if it works well)
Ah.. most important thing : NO BATTERY INCLUDED.
A quality electronic focus device suitable for most scopes

A very simple and effective way to remotely control the focus of most telescopes. Has several brackets adaptable to refractor and reflector scopes from almost every maker. The electric motor with variable pitch is very reliable and provides a solid and uniform grip in order to get and maintain the adequate focus position. Uses a regular 9V rectangular prism battery. The price is the best on the market.
