The Sky-Watcher EXPLORER-200P is a fantastic choice for intermediate-to-advanced astronomers but also suitable for the very serious adult beginner. With a much larger 200mm of light gulping aperture combined with its superb parabolic optics and superior resolving power, even fainter objects can be viewed. This telescope is a highly capable all-rounder with superb performance for the observation of the Moon, planets, nebulae, galaxies, star clusters, double stars etc. PARABOLIC PRIMARY MIRRORS SKY-WATCHER DELUXE MIRROR COATINGS FREE Fedex Priority 24 & 48 Delivery to Zone 1 Areas
Features High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal length reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, contrasty images, which are full of detail.
Most reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope. ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.
