The Sky-Watcher HERITAGE & SKYMAX Maksutov-Cassegrains are the ultimate ‘take-anywhere’ telescopes. They are also ideal if working space is limited. Despite their small dimensions they pack a powerful punch. Their High-Resolution, diffraction limited optical systems are multi-coated to maximize contrast and image sharpness. The Skymax Maksutovs come in apertures of 90mm, 102mm, 127mm, 150mm and 180mm, and are available either complete with equatorial mounts and tripods, or as tube assemblies only, which can be mounted onto a standard photographic tripod. Whether your requirement is for terrestrial or astronomical use, these compact scopes are the perfect companion. Tube material: Aluminium.
