Welcome to Electric Telescope Focusers

One of the biggest annoyances in high power photography or visual observing is the vibration inherent in any telescope. Touch the focusing knob to sharpen the image, and the telescope shakes and flutters like a leaf in the wind - sometimes for five or six seconds before settling down again. And no matter how gently you approach the job, it's a real challenge to move a cold and stiff focuser only the precise few thousandths of an inch needed to fine-tune the visual or photographic image - particularly when you're wearing gloves on a cold fall night, with the focus constantly changing as mirrors cool down and optical tubes contract. Electric focusers eliminate these problems
