Product Details

A small-aperture but extremely-portable ED scope at a GREAT price? The latest ZS 71 ED Doublet is here to fit all your needs!

Excellent mechanics, fit and finish, with the latest WO 2" Rack & Pinion 2-speed fine focuser. Improved focuser is so good that it replicates the smoothness and lack of backlash normally associated with a Crayford focuser, but with the huge advantage of much increased mechanical strength.

Lens Design

  • ED glass (Japanese imported Ohara glass) doublet air-spaced, in CNC machined ultra-high precision lens cell.
  • Each lens is Fully Multi-Coated with a special super-high transmission coating (STM Coating) on all surfaces.

Low CA

  • Fully baffled to block all extraneous off-axis light rays and prevent glancing reflections, increasing overall contrast.
  • 71 mm clear aperture and F/5.9 focal ratio.

Nothing Left to Chance

  • Perfect for Vixen-style mount dovetail bases. You can slide it directly into the mount without a dovetail plate if you like.
  • Pure William Optics quality fit and finish: powder-painted white CNC-machined aluminum tube
  • Drawtube travel length 80 mm with graduated scale.
  • Retractable dewshield, smallest size ever and enhanced portability!
  • Can mount a WO 2'' star diagonal and other 2" accessories.

Astrophotography ED Scope

  • Fast focal ratio for bright, high-quality astro-imaging.
  • Perfect for piggybacking as a guide scope

Wonderful WO Microfocuser

  • New rotatable Rack & Pinion focuser, smooth and precise, ideal during astrophotography; can be fully locked and will not flex or slip even with a very heavy camera combination.
  • Adjustable focuser tension.
  • Super-smooth and reliable 1:10 micro focuser for fine focusing during imaging and visual observations alike.
  • Aluminum fine knob protection cover is included.

Attention to Packaging

  • The basic package includes the OTA only.
  • Carry-on size: you do not have to leave this treasure home!
  • Two-year, no fuss warranty and constant customer service!
