Sky-Watcher Evostar 90 Refractor Telescope + AZ3 Mount #10723 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.

An ordinary single lens brings different wavelengths of light to different focal points. All Sky-Watcher Refractors are built with air-spaced two-element lenses, which reduce chromatic aberration more than standard doublet lenses.
