Specifications
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.
AIR-SPACED TWO-ELEMENT ACHROMATIC REFRACTORS
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.
