Explore Scientific Ultra Light Dobsonian 406mm
Modern 406mm grille dobson in all-aluminum construction

Modern secondary mirror construction - the secondary mirror mounting is tool-free and easy to adjust

Modern primary mirror cell - the primary mirror is adjustable from the front during observation and sits in a modern cell with radial roller bearing and 9-point floatation system

Large height wheels allow jitter-free movement even at higher magnifications

Hat and mountain bikes fit in the Rockerbox, the mirror box is complete with a lid for transport, so you have to transport only two aluminum boxes and a bundle of rods.

Extremely high rigidity of the construction

Baptismal test by all-aluminum construction: no more swelling pressboard boards by the exclusive use of aluminum and other metals

Light: The sandwich construction of aluminum profiles and aluminum sheets allows a dramatic weight reduction compared to the competition designs

Two radial main mirror fans for fast temperature adjustment

No type of telescope has changed amateur astronomy as much as the Dobsonian telescopes. Prior to John Dobson's presentation of the Dobsonian telescope, the vast majority of amateur telescopes consisted of small, primitive-mechanism lens telescopes - just enough to divine the polar ice caps of Mars or the rings of Saturn. Larger telescopes, such as Schmidt-Cassegrains, were reserved for a well-to-do clientele. The ingenious combination of simple but effective mechanics with the widest possible opening has given the Dobson telescope a unique triumphal procession worldwide. Nowhere do you get as much light for your money as with a good dobson. We have heeded the principle "Held together by gravity and driven by yoghurt power" (powered by gravity and powered by yoghurt energy) and created a completely redesigned modern dobsonian telescope with a lattice tube. The dismantling of the device allows trouble-free transport of this large device even in small cars - the structure is completely tool-free within a few minutes. The entire construction has been optimized for maximum rigidity without neglecting the weight. The combination of large height wheels with an optimized aluminum sandwich construction allows the finest correction movements at the highest magnifications. The focal position has already been prepared for the use of our coma corrector. The ideal workhorse for the deep-sky observer. A device with 406mm mirror diameter collects more than 3300 times as much light as the naked eye. Details on the planets are also visible to inexperienced observers, and countless deep-sky objects show structures. Bright star clusters are resolved to the core, and the sight of the Terminator on the moon becomes an unforgettable experience.
