Orion 8297 8-Inch f/3.9 Newtonian Astrograph Reflector

Orion 8297 8-Inch f/3.9 Newtonian Astrograph Reflector Telescope
- 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 reflectivity (94%) aluminum coatings with a protective quartz overcoat
- Also provides excellent visual views of everything from the Moon to the Messier list of celestial objects thanks to included extension adapters
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.
