Dobsonian telescopes are popular with amateur telescope makers for their ease of design and construction, portability, and their use of large optical mirrors. Pioneered by John Dobson in the 1960s, the instrument combines a Newtonian reflector telescope with a unique two-axis movable base.

It uses a primary mirror to capture and reflect light, a secondary mirror to direct light into an eyepiece, and a focuser to make fine adjustments for viewing. The telescope’s size is classified by the size of its mirror.
In this video you will see step by step how to make a 6″ Dobsonian telescope.This video describe the planning, design, and parts of the scope, as well as the process of building The scope.
Be creative! And, once your telescope is finished, be sure to join a local astronomy club to learn more about the sky and share your hobby with others.
