Evostar ED Apochromatic Refractor Telescopes
SIMPLY THE STATE-OF-THE-ARTPRO-SERIES is the name for the new generation of professional quality telescopes and mounts of the Sky-Watcher range, targeted at the most discerning and critical observers. ED Apochromatic Optics: ED glass elements minimise chromatic aberration, provide higher resolution and superior contrast. Colour fringing around objects is virtually eliminated with this type of optics. HEQ5 PRO & EQ6 PRO Heavy-Duty Equatorial Mounts: Specially designed to support larger telescope tubes, these high-precision mounts feature engraved setting circles and a latitude scale, built-in polarscope & retractable counterweight shaft. The worm gears are preloaded with ball bearings for smooth tracking and slewing. Auto-guiding interface is also included for long-exposure astrophotography. SkyScanTM PRO Computer-Control GOTO System: The hand controller allows pointing the telescope to a specific in the night sky at the touch of a button. The object database contains over 42,000+ objects, including complete M, NGC, and IC catalogues. The positioning accuracy is up to 1 arc minute with softwarecollimation error compensation. Period error correction (PEC) is included for astro-photography without auto-guiding. Stepper-Motor Technology: The built-in extra quiet stepper motors produce 800x high slewing speed and a resolution of 0.144 arc second. Crayford Focuser: The 2” Crayford focuser is backlash-free. The focuser wheels contain brushed-aluminium hubs with ridged rubber grip rings.

"I have used a great number of telescopes; some are good, some mediocre and some bad. To me the Sky-Watcher range of instruments are very good indeed, and suited to amateurs of all kinds – and they are not priced out of the market! Excellent value.
"Having tested and reviewed a wide range of astronomical telescopes over the last couple of decades, for me there's one manufacturer that's risen above the rest in terms of delivering a coherent range of uncompromising, well-conceived designs, embodying consistently good optics and sensibly engineered mounts at very competitive prices — that's Sky-Watcher!!"Ade Ashford BScAde Ashford has tested and reviewed astronomical equipment in a professional capacity for several publications, including Sky & Telescope, Astronomy Now & BBC Sky At Night Magazine.
