  • 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)
Ideal for High Power Daytime Terrestrial Observations as well as Astronomical Use!! Sky-Watcher EVOSTAR telescopes are classic two-element, air-spaced, achromatic refractors. They are outstanding, high-performance, high-resolution instruments manufactured to high standards of optical and mechanical precision. With their long focal lengths and breathtaking, diffraction limited optical performance, they are ideal for the detailed high-power study of the Moon, Planetary Surfaces and other objects in our solar system, giving crisp contrasty images. The intuitive and easy to use AZ3 Alt-Azimuth mount provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes.
