This quad full-frame reducer was designed for the SharpStar 94EDPH to effectively reduce the scope's focal ratio from 5.5 to 4.4.  The four-element air-spaced optical design produces an image circle of 50 mm, great for full-frame cameras!

The SharpStar 94EDPH Reducer uses M74 threads to connect to the telescope and M48 threads that can receive either a 48 mm T-ring for DSLR use or most astro-cameras.  Back focus is 55 mm.

This reducer also includes a 360-degree rotator to make image composition a whole lot easier!
