The William Optics 1.25" Erecting Prism is a high quality 90° image erecting BAK4 prism with anti-reflection coatings for premium refractors. The helical focuser mechanism on the top barrel makes fine focusing quick and easy.

Meticulously CNC-machined and anodized black, internally matte blackened and threaded for no stray light reflection, the 1.25" erecting prism is an exceptionally well constructed piece of equipment. The compression ring prevents eyepiece barrels from marring. Threaded for 1.25" filters
