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.
- 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.
- 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

- 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.
