The Ultimate in Light Gathering
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularised by John Dobson starting in the 1960s and credited with vastly increasing the size of telescopes available to amateur astronomers. The design is optimised for visually observing faint, deep-sky objects such as nebulae and galaxies.
Dobsonian telescopes are incredibly good light gatherers and are great for amateurs and professional astronomers alike. They are also very economical compared to other telescopes. The optical part of the telescope or OTA (Optical Tube Assembly) is the same as a Newtonian reflector telescope.
From its inception, telescope makers have been modifying the Dobsonian design to fit their needs. The original design fit the needs and available supplies of one person—John Dobson. Other people devised variants that fit their own needs, abilities, and access to parts. This has led to significant diversity in “Dobsonian” design.
A TableTop Dobsonian is just that – the perfect size to fit on your table! It is large enough to view night sky objects such as the Moon, planets, and bright nebulas and star clusters, yet compact enough to sit on a desk or store in your cupboard.
As it says, the tube is solid therefore making it robust and strong with no assembly time – ready to go!
“Classic” design tube assemblies require a large van for transport. Designers started coming up with disassembleable or collapsible variations that could be brought to a site in a small SUV, hatchback, or even a sedan. This innovation allowed the amateur astronomy community access to even larger apertures.
