Dave Says: "I've had my own WO Megrez 72FD for 7 years and its still my most used APO, and this is its successor. With the same bomb-proof build quality and now brought up to date with a precision rack and pinion focuser making it ideal for portable astro-photography."

"The ZS71 is the perfect partner to Sky-watcher's Star Adventurer when used with a BoDai-Global CloverThree Counterweight for longer exposures up to 10 minutes with practice. At 2.7kgs it's perfect as your second 'scope or even as your main refractor and is great to use terrestrially!"

It's like the Swiss Army Knife of small telescopes

There are lots of options for the ZS71 making it a great choice as your first all-round telescope. Fully baffled, for very low Chromatic Aberration (works fine on a Full Moon), and for a sharpness you don't get on cheaper refractors. You can use it for guiding, light enough for piggybacking and for use with lighter EQ and Alt-Az mounts for astro-imaging with DSLR or CCD.

Use it as a manual telephoto lens for great wildlife shots (we've tested it), and for visual birding and nautical use with their bright right-erecting prism. 

The Red Dot finder is a must-have add-on whatever you do.

Add the 0.8x Flattener 6 for half the exposure time with a fast f4.72 for amazingly detailed shots of M31 Andromeda and other deep sky objects with a truly flat field. For planetary work, you could use this with a QHY5-II 5P Colour camera and a Barlow for great images of the Moon and planets.

Visual astronomers are not forgotten either, with William Optics high quality range of SWA, UWA and XWA eyepieces, especially the 110º 5mm XWA eyepiece allied to either of their Carbon Fibre clad Dura Bright 99% Diagonals. 

Specification for Apochromatic Lenses

All WO refractors objective are double tested and inspected before shipping, these telescopes are free of coma and astigmatism.

Since all individual lens surfaces are machine coated sometimes it could have visual imperfections which do not affect the objective optical performance.

All William Optics Refractors carry a 2 year Warranty.

I spoke to David in depth about purchasing a new scope, what I wanted to do with it & what equipment I already owned for Astronomy. As I wanted to move into Astrophotography & combining my rather limited budget, Dave pointed me to the William Optics Zenithstar 71 ED. David's knowledge really helped me out as I had only ever owned a Reflector & an Alt Az mount. I can say without hesitation, the Zenithstar exceeded all of my expectations. It's Solid, Compact & beautiful to look at. It's Optics give a view that was sharp, brilliantly contrasted & left my jaw slightly ajar! This really is worth every penny & so is the information & knowledge from the Company. Thank you for your guidance, N Newby
