The Discovery 709 EQ is an excellent choice for beginners. This long-focal-length refractor with achromatic optics allows you to view the planets of the Solar System, study the Moon’s surface in detail and observe some deep-sky objects. During the day, this telescope can be used as a terrestrial spotting scope, providing magnified views of distant objects and thus enabling you to observe nature.
One of the strengths of this model is its equatorial mount with knobs for micrometric movement control. This will help you master the precise pointing and tracking of celestial objects. As for the optics, this is an achromatic configuration and is therefore free from chromatic aberrations, which are otherwise common in refracting telescopes. The lenses are treated with an anti-reflective coating, ensuring clear, crystal-clear images. Observations can be made at different focal lengths. The kit includes three eyepieces, a mirrored diagonal, a right-angle eyepiece for terrestrial observations and a powerful Barlow lens.
All these accessories can be conveniently placed on a tray situated in the centre of the tripod legs, so that they are always within easy reach. The telescope features a standard 1.25-inch focuser, allowing you to experiment with a wide range of additional accessories if required. Another special feature of the Discovery Spark 709 EQ is the educational book ‘Space: Not Empty’. This illustrated guide will help users learn a great deal about the sky before they begin observing, or allow them to brush up on their knowledge.
