Tele Vue’s RFL-4087 is a 0.8x Reducer/Flattener for imaging with a Tele Vue 102, 102is and any other 800-1000mm focal length refractor. It provides a corrected imaging circle for cameras with a full frame sensor (35mm diagonal) and below, whilst also increasing your light gathering ability by providing a reduction in effective focal ratio. For example if imaging with a native focal ratio of f/6, adding the RFL-4087 would provide an effective focal ratio of f/4.8.
