  • Fully multi coated 50mm f/4 (focal length = 200mm) achromatic objective
  • Designed for use with small-chip CCD autoguider cameras having a 1.25" nosepiece
  • Can be used as an optical finder but most eyepieces will require an 0.5"-1" extension tube to reach focus. Eyepiece and extension not included
  • 90-deg erecting prism diagonal with helical focusing available separately to convert guidescope into a right angle finder

Mechanical Features

  • 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 (without eyepiece) = 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)

Please note: Any camera/accessory inserted into this guider will rotate as you rotate this guider's focuser. Be careful to avoid twisted cables.

Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.
