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 CoverThree Counterweight for longer exposures up to 10 minutes with practice. And why not add a WO soft Carry bag. At 2.7kgs it's perfect as your second 'scope or even as your main refractor and is even 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.
Comes complete with 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.
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.
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.
