Description

William Optics 1.25" 90° Erect Prism for Cat 61 WIFD

Transform your observing experience with this 90° erect-image prism diagonal, ideal for both terrestrial and astronomical use. Designed specifically for compact refractors and catadioptric telescopes like the Cat 61 WIFD, this diagonal delivers correctly oriented images—right-side up and left-to-right accurate—for natural viewing.

Features:

  • Standard 1.25" Barrel: Compatible with any telescope accepting 1.25" accessories.

  • 90° Viewing Angle: Comfortable viewing position, perfect for targets near the zenith or daytime spotting.

  • Erecting Prism System: Produces a fully corrected image, unlike standard star diagonals.

  • High-Quality Optics: Multi-coated prism surfaces minimize light loss and ensure crisp, bright images.

  • Durable Housing: Compact, lightweight construction with a precision-fit nosepiece and eyepiece holder.

  • Thumbscrew Securing: Keeps your eyepieces safe and secure during use.
