The GSO 16 Inch Truss Dobsonian Telescope is designed for serious visual astronomy, featuring a large 406 mm aperture and 1800 mm focal length at f/4.5. Its large parabolic primary mirror gathers tremendous amounts of light, making it excellent for observing faint nebulae, globular clusters and galaxies under dark skies.
 
The truss design makes this large aperture telescope easier to transport and assemble, while the smooth Dobsonian mount allows you to easily navigate the night sky by moving the telescope manually. The 94 percent enhanced aluminum coating, cooling fan and 18 point mirror cell help maximise optical performance.
