Modern 406mm truss-dobsonian telescope in full aluminium construction
  • Modern secondary mechanics - the collimation is easily achieved without tools and keeps collimation well during transports
  • Modern primary mirror cell - the telescope mirror can be collimated from the front while looking through the eyepiece and is supported by a modern floatation system with radial roller bearings
  • Large powder coated altitude wheels provide smooth and precise movement even at high magnifications
  • Secondary unit and altitude wheels fit into the rocker box and the mirror box includes a cover for transport so that the whole telescope breaks down into only two aluminium cases and the trusses
  • Extremely high rigidity construction
  • Dew-resistant because of aluminium construction: no deforming press board due to the exclusive use of metals
  • Lightweight: the aluminium profile/aluminium plate construction reduces the weight to about half of the mass of most press board designs of this price range
  • Two large radial fans for fast thermal equilibrium
  • Scope of delivery: Telescope, Manual, Reducer 2"/1.25", Red dot finder, Stray light shield for secondary cage, Main mirror collimation tool, Battery compartment with bag for fans, Extension tube for focuser
Delivery period: 1-3 working days.

Ultra Light Dobsonian 406mm GENERATION II - with completely redesigned and improved construction.

No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 406mm aperture gathers more than 3300-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.
