Ultra Light Dobsonian 500mm GENERATION II

EXPLORE SCIENTIFIC Ultra Light Dobsonian 500mm GENERATION II

Product description

Modern 500 mm 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
