Product description Our 8"aperture deep-sky imaging specialist boasts features
usually reserved for much pricier astrophotography telescopes. In fact, the
Orion 8" f/3.9 Newtonian Astrograph's powerful imaging performance easily
exceeds what's achievable with many premium apo refractors costing thousands
of dollars more. Its 8" parabolic primary mirror has 800mm of focal length,
making the fast f/3.9 Newtonian an ideal wide-field astrophotography
telescope. A substantial 70mm minor axis secondary mirror provides full field
illumination to CCD and/or DSLR cameras for efficient astrophotography
performance. Both primary and secondary mirrors boast enhanced reflectivity
(94%) aluminum coatings with a protective silicon dioxide (quartz) overcoat.
Three easy-grip, push-pull collimation hand knobs on the primary cell make
collimation adjustments easy. Once aligned, three locking thumbscrews secure
the 8" parabolic mirror. Images acquired with the 8" f/3.9 Newtonian
Astrograph will exhibit maximum contrast thanks to sophisticated telescope
features any astrophotographer will appreciate. Nine precisely positioned
baffle rings along the inside of the reflector optical tube minimize internal
reflections of pesky off-axis light for pristine imaging performance. To
further optimize contrast and avoid off-axis light intrusion near the front of
the telescope, the dual-speed 2" Crayford focuser has been installed a full
6.3" back from the front of the 30" long reflector optical tube. From the
Manufacturer Capture excellent astrophotos with our 8" aperture imaging-
optimized f/3.9 Newtonian astrograph reflector telescope. Big 8" (203mm)
aperture and fast f/3.9 focal ratio provides powerful astrophotography
performance. Nine internal baffle rings, extended tube length in front of the
focuser, and flat-black interior work together to provide maximum image
contrast. Both primary and 70mm minor-axis secondary mirrors feature enhanced
