Description

The Stargate Dobsonians represents the ultimate combination between light gathering, precision and portability for outstanding performance and resolution. The truss structure is compact, allowing for easy transportation while you’re in search of the perfect dark, pristine sky. The outstanding light gathering of the mirror and the superior resolution allow amazing journeys through the universe, offering spectacular observations of tangled gas filaments in nebulae, fine galaxy details and remarkable planet structures. Despite the size of the mirror, the telescope is easy to assemble following the step by step instructions and video.

To top it off, the Sky-Watcher Stargate is equipped with a 2″ Crayford dual speed focuser for smooth and precise focusing, and a focuser-locking screw.

PARABOLIC PRIMARY MIRROR

The most extraordinary feature of the Stargate is the technology used in the mirrors. They are made up of borosilicate glass that has a very low expansion coefficient, reducing the stresses caused by thermal gradients. The primary mirror uses a special lightweight technology. In fact, the mirror is extremely light and thin, but the glass ribs beneath minimise the glass deformation, thus allowing continuous high performance in all the telescope angulations. Moreover, the small thickness of the mirror allows a much quicker cooling time compared to the standard monolithic mirrors. The secondary mirror has a honeycomb structure that follows the concept of the primary mirror: lightweight, rigid and quick to cool down.

Both the mirrors are aluminised and in order to protect the reflective treatment over the years, the coatings are protected by a thin layer of quartz (silicon dioxide). This protection is needed as the mirrors are exposed to external elements due to their position in an open truss tube. Sky-Watcher is one of the few companies in the world that use this particular technology.
