Collection: Telescope Focal Extenders & Reducers | Telescope Wolves

Focal extenders and focal reducers allow you to change the effective focal length of your telescope, giving you greater flexibility for visual observing and astrophotography. Focal extenders increase magnification for detailed planetary and lunar viewing, while focal reducers shorten focal length to provide wider fields of view and faster imaging.

At Telescope Wolves, our focal extender and reducer collection includes Barlow lenses, focal extenders, and focal reducers from trusted astronomy brands. Each item is selected for optical quality, mechanical precision, and compatibility with a wide range of telescopes, cameras, and accessories.
