Product Details

Modern 305mm 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 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
  • Truss-Dobsonian Telescope in full Aluminium construction
  • NEW: Slider bearings made from TEFLON und GFK for smooth and precise movement
  • NEW: Improved main mirror cell with completely redesigned mechanics
  • NEW: Altitude bearings with new designed brake and friction system
