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

Explore Scientific ultralight 305mm dobson generation II

Uitstekende scoop,zeer goede optiek. Mechanisch enkele minpuntjes maar niet om wakker van te liggen.
De red-dotfinder heeft geen standaardbevestiging zodat er geen andere zoeker kan bevestigd worden. Collimeren is in een oogwenk gebeurt dankzij de handige collimatie-tools.

Dus blij met de aanschaf van deze telescoop!
