ALTAZIMUTH NEWTONIAN TELESCOPE ➤ SCHOTT Supremax 33 optics ➤ optical diameter: 460 mm ➤ useful diameter: 450 mm ➤ focal ratio: f/4 ➤ primary mirror thickness: 35 mm ➤ minor axis secondary mirror: 100 mm ➤ axial cell cooling system ➤ multi-fan removal of the mirror surface boundary layer ➤ carbon truss with self-centering conical couplings ➤ lateral supports (six) designed for altazimuth instruments ➤ zero deformations The NortheK Rapido 450 is designed to be disassembled into essential parts for transport in a small car. Each component is equipped with its own case, facilitating transport and assembly. The main element weighs 27 kg. Incorporated mechanical devices and the precise execution of each component allows for the collimation of the optics with extreme ease, maintaining collimation throughout an observation session while eliminating twisting and bending, regardless of the weight of the accessories used. The very thin primary optic allows for rapid acclimatization and ensures thermal stability throughout the night. Two bars equipped with sliding weights allow for the perfect balance of the telescope and accessories. On demand, it is also possible to modify the support to mount the telescope on an equatorial platform. This instrument is composed of aluminum, carbon and steel, each perfectly selected according to strict mechanical standards. It is undoubtedly the best altazimuth Newtonian on the market.
