Product Description
Skywatcher Skyliner-250PX FlexTube 10 inch Dobsonian Telescope
Dobsonian telescopes offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in 1970's, is a simple and efficient 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 that 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 use frictional materials which allow it to be moved 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. Sky-Watcher Dobsonians provide excellent all-round performance for the observation of the Moon and Planets and Deep Sky Objects such as Galaxies and Nebulae.
