Dobson telescope N 254/1270 Ultra Light DOB

Dobsonian telescopes are among the most practical instruments in astronomy. They are of simple construction and yet a brilliant idea. They essentially consist of two parts: firstly the optics, which in most cases is a solid tube or truss tube design; and secondly the mount, a wooden box (also called a 'rocker box') which sits on the ground and into which the telescope is inserted. This design allows you to begin observing sessions immediately without first having to spend time setting up and aligning a complicated mount. The basic idea of the Dobsonian design came from the wish to have a big telescope at a low price, a wish that has succeeded brilliantly. A true fan base has developed since the invention of the Dobsonian telescope which is dedicated to these instruments and their fascinating simplicity and to the idea of 'high performance at low price'.

Explore Scientific offers lightweight tubular aluminium frame which is optimised for transport and quick deployment.

• The mount for the secondary mirror can securely adjusted without tools.
• The primary mirror can be adjusted anteriorly during observation and sits within a modern cell with radial roller bearings and a 9-point flotation system
• Large altitude bearings allow for quiver- and judder-free movements, even at large magnifications
• The cap and altitude bearings fit inside the rockerbox, the mirrorbox has a lid for transportation, so that only two aluminium boxes and one bundle of poles have to be transported.
• Extremely high structural rigidity!
• Dew-resistant due to aluminium construction: No more bulging press boards thanks to exclusive use of aluminium and other metals
• Two radial primary mirror fans for rapid temperature adjustment
