Product Details

Closeout - All Sales Final

Important Note: This guidescope has only 6.2mm of back-focus available. Hence, it can only be used with 1.25" cylinder-type or "Mini" cameras from QHY, ZWO, SBIG, etc. Please check your camera or autoguider's back-focus requirements to ensure compatibility before you purchase this.

All new, unique, fully multi coated WO 50mm f/4 guiding scope with 1.25" RotoLock adapter that fits perfectly on your William Optics telescope. This item requires that your guiding camera should have a 1.25" nosepiece.
