A Battery Free Electric Focuser

Building an electric control for your focuser can help you achieve focus easier & quicker. With an electric control focuser, there is no need to touch the telescope and so you don't induce telescope wobble, which in turn, speeds up the task of focusing. You can buy electric focusers but they are expensive and can be difficult to mount (especially on refractors). This simple idea, is neat, easy to implement with parts bought from Maplin's and despite being an electric focuser, it doesn't use batteries!!!!!!
