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
