Evostar ED Apochromatic Refractor Telescopes

• ^"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.
  Use them and enjoy them.^"Sir Patrick Moore CBE FRS (1923 to 2012)
• ^"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 BSc_{Ade Ashford has tested and reviewed astronomical equipment in a professional capacity for several publications, including Sky & Telescope, Astronomy Now & BBC Sky At Night Magazine.}

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.

SkyScan^TM 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.

 

World Exclusive Co-Branding Agreement with Schott Selected high-end Sky-Watcher telescopes benefit from the inclusion of Schott glass in their construction. Schott is the recognised world leader in glass utilised for precision optical lens systems, including medical instrumentation and famous brand camera lenses. Sky-Watcher’s parent company signed a worldwide exclusive telescope co-branding agreement with Schott in March 2008.
