I have an APO triplet of Roger’s that is a prized possession. Roger had built the ‘scope to provide a home for a beautiful 12.5″ f/5 mirror he had made. A Dobsonian telescope is an alt-azimuth mounted Newtonian telescope design popularized by the amateur astronomer John Dobson starting in the 1960s. Standard on all Truss-Dobsonians 12.0" and larger. The mirror is gorgeous, as is typical for Roger who is one of the best opticians I know. He enabled the average Amateur Telescope Maker “ATM” to create a large and very stable telescope with common workshop tools. This oustanding innovation allows the user to keep their scope assembled into two major sections, which allows for quicker assembly in the field as compared with other similar Truss-Dobsonian designs. Starstructure telescopes are designed for portability and yet maintain the rigidity required for a high quality observing experience. Beneficial Features: large aperture; red-dot viewfinder; easy to transport; powerful magnifying features; Buy On Amazon. Our Mission. It is very easy to set up and to tear down. 3 easy payments of $666.66 With payment plan. Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The mission of Starstructure has always been to provide the amateur astronomy community with top quality products. Mechanically the scope had a few problems. John Dobson really started something with his Dobsonian “Dob” telescope design. An 8 inch Zambuto mirror is $1100 an 8 inch Royce is $750 to give you an idea of top end range on mirrors. 1. This value-packed bundle includes the 12" XX12i Truss Tube IntelliScope Dobsonian, a specially designed Light Shroud to block stray light and a 3-piece Case Set to protect the optical tube sections during transport and storage. Orion 10019 SkyQuest XT10i IntelliScope Dobsonian Telescope. Since then Dob’s have evolved from a heavy boxy structure to elegant lightweight designs with truly excellent optics. "best 8 inch dobsonian" and "my price limit is $600" are a contradiction in terms. The best thing is that you won’t need any tools for the setup process. Starstructure Telescopes has been on the leading edge of Truss Dobsonian manufacturing and advancement since 1998. Some time ago my friend Bill Lofquist bought a dobsonian telescope from Roger Ceragioli. Thanks to the open truss design of this 12-inch Dobsonian telescope you won’t have any trouble with the transportation process. Built with professionals in mind, Orion has yet again, pushed the envelope and put a modern spin on these classical telescopes, allowing for even finer details to be examined while observing deep sky objects. Above 12” a truss structure is nearly a requirement for portable use, as the optical tube of a 16” tube Dob weighs around 100 pounds and is the size of a water heater. $1,999.99. Best 10 Inch Dobsonian Telescopes. As shown at left, the scope can be transported or stored ready for use in this configuration. Here are our reviews of the best 10 inch Dobsonian telescopes. A truss structure increases the cost of the instrument dramatically - but at the same time it makes other enhancements seem more worthwhile.
