The Third Planet Optics 0.5x focal reducer screws on to any 1.25-inch eyepieces barrel and provides a nominal reduction of 0.5X. This package comes with a 25 mm extension tube for further reduction. The actual focal length reduction will vary a little depending on where the focal reducer is placed in the optical path. The reducer features a 2-element fully multi-coated optical design and blackened lens edges in a black anodized aluminum filter cell. It also has additional 1.25-inch filter threads, so you can screw/stack additional filters on to this reducer. Will work with all Meade DSI cameras, the Meade LPI, the Celestron NexImage, the Orion StarShoot cameras and most CCD cameras that use a 1.25-inch nosepiece!
