Product Details

Here is William Optics' complete 50mm finder and guidescope kit in one complete package! Depending on your application, just use the 1.25" diagonal or extension tube with the main finder. This set contains:

  • 50mm finder optical tube
  • 1.25" 90-deg erecting prism diagonal with helical focuser for use as a right angle finder
  • 1.25" extension tube with helical focuser for CCD autoguiding

Optical Features

  • Fully multi coated 50mm f/4 (focal length = 200mm) achromatic objective
  • Right Angle Finder Mode:
    • 1.25" 90-deg high-quality erecting prism diagonal included for use as a right angle finder
    • Provides 10x magnification with a 20mm eyepiece or 8x with a 25mm eyepiece
  • Straight-Through Guider Mode:
    • Designed for use with small-chip CCD autoguider cameras having a 1.25" nosepiece
    • Can be used as a straight-through optical finder but most eyepieces will require a separate 0.5"-1" extension tube to reach focus.
  • Eyepiece not included

Mechanical Features

  • Right Angle Finder Mode:
    • 1.25" diagonal features helical focusing with 15mm (0.59") of focus travel
    • Diagonal / eyepiece are rotatable
  • Straight-Through Guider Mode:
    • 1.25" holder features brass compression ring and 3 locking screws to securely hold your camera
    • Helical focusing with 15mm (0.59") of focus travel (be careful not to exceed this or the eyepiece holder will separate from the finder)
    • Holder / camera are rotatable
  • White powder painted with excellent fit and finish that are the hallmark of every William Optics product

Mechanical Specifications

  • Tube diameter = 54.6mm (2.15"); Dewshield diameter = 58.1mm (2.29")
  • Tube weight (with diagonal / without eyepiece) = 15.9oz (451g)
  • Tube weight (with CCD extension tube / without camera) = 15.0oz (425g)

Finder Rings / Bracket

  • 6-point 50mm finder bracket with delrin tipped screws included
  • Dovetail base/screw to mount bracket on all William Optics refractors included
  • Bracket can also be mounted on other telescopes that use a 5mm or 6mm mounting screw; not compatible with Vixen/Synta-style base
  • Bracket weight = 9.5oz (269g)

* Note that not all eyepieces will reach focus in this or any other finder due to the limited focus travel range. Finding a compatible eyepiece that reaches focus may require some trial and error. This is an issue with any finder/spotting scope/guidescope that can accept external eyepieces, and not just with this item.
