About the Orion SkyView Pro 8" Equatorial Reflector Telescope...
The Orion SkyView Pro 8" Equatorial Reflector Telescope has long been admired for its winning combination of outstanding optics and a rock-solid Orion Telescope Mount. This is one big Orion Telescope, capable of providing big, bright views of cosmic curiosities.
The reflecting Orion Telescope features an 8" (203mm) parabolic primary mirror, which gives you a whopping 73% more light grasp than a 6" telescope. More light gathering ability means the Orion SkyView Pro 8" Equatorial Reflector Telescope will display brighter, sharper images for both visual study and astrophotography pursuits.
You''ll be delighted with beautiful views of the night sky when using the Orion SkyView Pro 8" Equatorial Reflector Telescope. You can go way beyond the Messier catalog with this telescope! Thanks to its substantial aperture, the 8" SkyView Pro Orion Telescope gathers enough light for pleasing views of faint and elusive deep sky objects which you simply cannot detect with smaller diameter instruments. When aimed at the Moon or planets of the solar system, the Orion SkyView Pro 8 Equatorial Reflector telescope''s 1000mm focal length (f/4.9) gives you the ability to resolve fine detail at high power.
Supreme stability for the big 8" aperture reflector is supplied courtesy of the included SkyView Pro Equatorial Orion Telescope Mount. Equatorial mounts, commonly called EQ mounts for short, can be aligned with Polaris, the North Star, so that the attached Orion Telescope can easily follow celestial objects as they appear to migrate across the night sky using either manual slow-motion controls or an optional electronic motor drive system (motor drive sold separately). If you'''re interested in using the Orion SkyView Pro 8" Equatorial Reflector Telescope for astrophotography, you'''ll need an optional motor drive to capture extended exposures of the night sky. The stalwart SkyView Pro Equatorial Orion Telescope Mount and steel tube tripod provide a stable platform that''s so smooth you'''ll think the telescope is floating on air.
The Orion SkyView Pro 8" Equatorial Reflector Telescope features a precise 2" Crayford-style focuser with a 1.25" telescope eyepiece adapter and focus lock knob. Standard accessories that come with the 8" reflector telescope include an 8x40 finder scope, two 1.25" Sirius Plossl telescope eyepiece (25mm and 10mm focal lengths), collimation cap, and a dustcap for the front. The Orion Telescope even has a center mark on the 8" primary mirror for easy collimation, or alignment, of the optics. The SkyView Pro Equataorial Orion Telescope Mount features a handy tripod spreader tray that keeps the tripod stable and can hold accessories like telescope eyepiece when they'''re not being used.
This standard, non-computerized configuration of the Orion SkyView Pro 8" Equatorial Reflector Telescope can be upgraded to GoTo capability at any time by purchasing the optional GoTo Upgrade Kit for SkyView Pro EQ Orion Telescope Mounts (sold separately).
