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 Evostar is mounted on a Bresser Exos Mount with Skywatcher dual axis drives. The award winning Sky-Watcher Evostar 120 (Exos) is a fantastic choice for intermediate-to-advanced astronomers but also suitable for the very serious adult beginner.
