Sky-Watcher Collapsible Dobsonian 8"
|The Sky-Watcher 8" Collapsible Dobsonian is a telecope to consider if you minimal volume for travel purposes. |
The Sky-Watcher Dobsonian utilizes quality components throughout. Pride of workmanship manifests itself in 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.
On each primary mirror, and elliptical diagonal mirror aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied. Dust covers help keep your Dobsonian clean when not in use.
An 8x50mm right angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping. The standard-equipment backlash-free 2-inch Crayford focuser insures ultra-smooth focusing adjustments. Multi-coated, 4-element Plossl eyepieces (25mm and 10mm) provide a spacious 52 degree Apparent Field of View.
The mechanical and structural components of the OTA exhibit rigid construction and outstanding stability. The mount construction is sturdy and rigid. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance the observer's viewing experience.
