- Description
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 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
