”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

SKY-WATCHER ASTRONOMICAL TELESCOPES

Ade Ashford Says...

"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. He is currently living in New Zealand and is an astronomer at Mt John Observatory, Lake Tekapo.

SIMPLY THE STATE-OF-THE-ART


PRO-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.

PRO-SERIES products are manufactured to extremely high levels of optical and mechanical precision, undergoing very strict quality control procedures and testing by specially assigned technicians, to ensure the highest standards of quality and performance are consistently maintained.

ED APOCHROMATIC REFRACTORS

Premium quality, high performance telescopes for planetary and deep-sky observaions as well as astrophotography and CCD imaging. The two-element objevtive lens is fully multi-coated and utilises special, extra-low dispersion FPL-53 fluorite glass for the virtual elimination of false colour. Performance of these telescopes will both delight and surprise the most critical observer, and can be genuinely compared to Apochromatic telescopes of other brands in price brackets normally way beyond the reach of the average user.



ED Apochromatic Optics: ED Fluorite 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 13,400 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.

Note: 120mm models due Autumn/Winter 2005

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.

Schott glass is currently present in the EVOSTAR-ED APO Refractors, the SKYMAX-150 & 180 PRO Maksutov-Cassegrains, EQUINOX ED APO Refractors and the EXPLORER-190MN PRO Maksutov-Newtonian

EVOSTAR-100ED DS-PRO (OTA)
100mm (4”) f/900 Fluorite ED Apochromatic Refractor Telescope  

The new EVOSTAR DS-PRO Series ED Apochromatic refractors in their stunning Black-Diamond livery, house premium optics of the same quality and performance level as our now legendary Equinox series, making them superb instruments for both imaging and visual observations.

Apochromatic Refractors, due to their unobstructed, text-book like diffraction patterns, produce the sharpest, highest quality optical imaging available, bar-none, aperture for aperture, of any telescope optical system.

These high-end telescopes all feature a doublet objective lens. One element is made from premium Japanese Ohara FPL-53 Extra-Low Dispersion (ED) glass, which virtually eliminates chromatic aberration to deliver true colour reproduction. Top quality Schott glass is utilized for the Crown element.

Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied, to ensure optimum light through-put of approaching 99.5%!!

The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.

EVOSTAR DS-PRO ED APOCHROMATIC REFRACTORS

Ade Ashford Says…

Ade Ashford Says…
"While the traditional achromatic refractor offers good correction for chromatic aberration (false prismatic colours around bright objects), the discerning observer and astrophotographer will appreciate the near-perfect optical correction provided by the EVOSTAR DS-PRO series. Not only do these instruments look stunning in their black-diamond livery, but their objectives composed of Japanese FPL-53 ED and Schott crown glass will deliver image quality to match."

  • “Great all-round package...We were pleased to see the stat Altair pin-sharp across 85% of the field of view, with only slight trailing off near the edges...On deep-sky objects, the dual-speed Crayford focuser allowed us to gain fine, crisp views; particularly noteworthy was the Dumbell Nebula M27. The wide field of view also produced fine vistas of the Andromeda Galaxy...The focuser’s 1.25” adaptor had a nice touch: a DSLR camera attachment for imaging. Overall this telescope packs a lot of punch...a complete setup with lovely crisp optics” BBC Sky At Night Magazine
