The orion build-a-scope 12" intelliscope truss dobsonian telescope improves on the already stellar features and performance of our standard xt12 intelliscope dobsonian and its build-a-scope cousin. we outfitted this telescope with larger, 8" altitude bearings for smoother tube motion.. How to build a 12.5 inch closed tube dobsonian telescope. i began building it in the spring of 2008, but the bulk of the work was done in july of 2008 with first light occurring on july 25. this instructable describe the planning, design, and parts of the scope, as well as the process of building the scope.. A dobsonian telescope is an altazimuth-mounted newtonian telescope design popularized by john dobson starting 53 years ago in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers. dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components.
It is now very cheap to purchase dobsonian telescopes off the shelf, and fully equipped with lenses and finder scopes. $450 will buy a new 150mm (6 inch) telescope. at that price it is hard to justify building one.. The dobsonian telescope, a practical manual for building large aperture telescopes tells how you can build a state-of-the-art dobsonian telescope using readily available materials and supplies. every step of construction is detailed in photographs and diagrams, and the underlying ideas are carefully explained.. To construct my truss-tube telescope, i have generally followed instructions outlined in the book "the dobsonian telescope: a practical manual to building large aperture telescopes" by david kriege and richard berry (willmann-bell, 1997)..
