This base is what makes the XT10 Classic telescope a Dobsonian reflector by name, as the first such design was made by ingenious "sidewalk astronomer" John Dobson. Refractor telescopes refract, or "bend" incoming light to a focus by means of an objective lens. The XT10 Classic is refreshingly easy to use thanks to its simple, "point-and-view" Dobsonian design. Note: ...
