Used Reducer, in excellent condition!

The Founder 0.8X Focal Reducer was designed to reduce the effective focal length of the FOT86 or FOT106 refractors, but it will work with pretty much any f/5 to 5/7 refractor.  The RED0.8X has interchangeable M42 male and M48 male mounting threads.  The optics, which are fully multi-coated, have a clear aperture of 38 mm.
