Product Info
Manufacturer Description
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!

Very good small, compact refractor
Pros:Quality Lenses,Easy to Use,Accurate,Compact
Cons: Comments:This refractor is a precision telescope with a great rack and pinion focuser that locks in place. The focuser is very smooth and does not drift. The star images I saw throught it were pin point and with good eyepieces, stars were round to the edge of the field. The fit and finish were outstanding as on all WO products. One small drawback was the mounting foot. It arrived fairly loose and when examining the length of the two screws that hold on the foot, they appeared to be slightly short, not fully engaging the shallow thread depth. I replaced the screws with longer ones, careful not to bottom out on the focuser tube and then tightened them. The foot was then secure and I have used this scope to guide with several times and experienced no flexure or movement in any way. I am very happy with this scope.

Dec 14, 2013Precision Optical Instrument
Pros:Lightweight,Quality Lenses,Strong Construction,Compact,Easy to Use,Accurate
Cons: Comments:In my opinion, this high quality optical instrument is very portable, solid construction, precision, well engineered, easy to set up and use. The focuser allows fine tuning, with a great feel and will give excellent, clear wide field views and photographs of the starry sky. Highly recommended.

Jun 2, 2013Outstanding OTA
Pros: Cons: Comments:Since my purchase of this scope, it has gotten more use than the other scopes I have (10" f4.7, 6" f/8, 5" f/7.7 newts and a ES AR-127 refractor). Mainly due to its portability and outstanding optics. I have not delved into AP yet, but for binoviewing and just some kick back star gazing, I don't think I could have made a better decision. The OTA is sleek, light, well constructed and with the rotatable focuser, plus the retractable dew shield, I haven't any complaints on what you get for the price. It is definately not for detailed planet viewing, but for widefield viewing, bviewing, AP and some great moon viewing. Highly recommended.

Mar 22, 2013Zenith Star 71mm f/5.9 Doublet ED 2013
Pros:Accurate,Compact,Lightweight,Easy to Use,Strong Construction,Quality Lenses
Cons: Comments:Excellent for portability, stargazing, and astrophotography, providing a widefield view. Solid built with excellent components. Focuser appears to be very strong and accurate, but does give more resistance than a standard crayford focuser. Well Pleased.
