Explore Scientific DOB1645 Truss Tube Dobsonian Telescope
No telescope type has changed the hobby quite as much as the Dobsonian. Before the popularization of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain, were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope its unique popularity worldwide.
This DOB1645 Truss Tube Dobsonian Telescope is a Generation II telescope with all the updates and offers the largest aperture per dollar of any telescope type. Nowhere do you get as much light for your money like a good Dobson. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars. The entire structure has been optimized for maximum stiffness and minimal weight. The combination of high-altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications.
- The DOB1645 Truss Tube Dobsonian Telescope is one of the most portable large Dobsonian telescopes on the market today.
- This Truss Tube Dobsonian with a 16-inch primary mirror and 1829mm of focal length can be transported easily in a compact car.
