  • Sir Patrick Moore CBE FRS"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)
  • 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 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.
Ideal No Fuss, Grab-and-Go Telescope for Easy Visual Astronomy as well as High Power Daytime Terrestrial Observations!! The Sky-Watcher EVOSTAR-90 is a classic two-element, air-spaced, achromatic refractor. With its long focal length it is ideal for the detailed high-power study of the Moon, Planetary Surfaces and other objects in our solar system, providing crisp contrasty images. The supplied erect image diagonal provides an upright, fully corrected image allowing the telescope to be also used for terrestrial observing. The well engineered and easy to use AZ PRONTO Alt-Azimuth mount provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes.
