Sky-Watcher Dobsonians epitomize Ease-of-Use:
The Sky-Watcher 203 mm (8-Inch) is one of the greatest available experiences in amateur astronomy.
The included 8 x 50 mm right angle optical viewfinder provides both magnification and light-gathering to help narrow your search. The backlash-free 2-inch Crayford Focuser ensures ultra smooth focusing adjustments, and the multi-coated, 4-element Plossl eyepieces (25 mm and 10 mm) provide a spacious 52-degree Apparent Field of View.
To guarantee mechanical ease-of-use, Sky-Watcher USA uses a high-performance Teflon bearing system in both axes combined with tension adjustment to facilitate friction, assuring smooth vertical and horizontal manual movement without a hiccup. Sky-Watcher's Teflon bearing system is preferable to the use of ball-bearings, as ball-bearings make unintended hiccups in movement more common. Fortunately, at low power, deep-space objects leisurely drift through the field of the Sky-Watcher 8-inch Dobsonian, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view.
Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece, low-hassle OTA design is mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-trans-portability.
The Sky-Watcher Dobsonian Telescope Uses Quality Components Throughout:
The Sky-Watcher 8-inch Dobsonian utilizes quality components throughout. High-quality standards of optical and mechanical fabrication. The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast, and properly corrected optics show minimum alterations to the optical wave-front.
Aluminum is vacuum-deposited to the front glass surface on each primary mirror and elliptical diagonal mirror and then over-coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied. Dust covers help keep your telescope clean when not in use.
The mechanical and structural components of the OTA and mount exhibit rigid construction and outstanding stability. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance the observer's viewing experience.
