These instruments offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the late 1970’s, is a very simple but effective method of mounting a Newtonian Reflector, based on the alt-azimuth principle. Fast and easy to set up, the Dobsonian mount consists of a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and to use frictional materials, which allow it to move easily when nudged but to stay in position when not. The mount is designed to be driven by hand as opposed to slow motion controls. Tube material: Aluminium.
ADVANCED FEATURES All Sky-Watcher Dobsonian models feature 0.5mm Ultra-Thin Secondary Mirror Supports to reduce diffraction spikes & light loss, and high quality Paraboloidal primary mirrors to eliminate spherical aberration.
Sky-Watcher Dobsonians feature a unique patented Tensioner/Carrying handle. By lifting the handles together, you can easily carry the whole unit in an upright position with the help of a friend.
SKYLINER PARABOLIC DOBSONIANS (STANDARD TYPE) Ade Ashford Says... "For the largest aperture telescope and light-gathering capability for your money, look no further than a Sky-Watcher Dobsonian. The Skyliner range feature the same high-precision Newtonian optical tube assemblies found in the Explorer series, coupled to a stable, non-motorised mount that's intuitive to use. A rugged, no-nonsense design for the practical observer that delivers all-round performance on the Moon, planets and dazzling deep-sky performance -- especially in the larger apertures."
