Orion 6 Inch f/4 Newtonian Astrograph Reflector Telescope

Our 6 inch aperture imaging reflector is loaded with useful features useful features to help you capture high-resolution images of the night sky. With very fast f/4 optics and 94% reflectivity coatings, the Orion 6 inch Newtonian Astrograph will help you acquire outstanding high-resolution images of deep-sky objects with delightfully short exposure times so you can get great results in less time. What's more, this compact imaging specialist is conveniently lightweight at just 12.7 lbs., so it doesn't require a huge mount to support it.

Its 6 inch parabolic primary mirror has 610mm of focal length, making the fast f/4 Newtonian an ideal wide-field astrophotography telescope. A substantial 63mm minor axis secondary mirror provides excellent field illumination to CCD and DSLR cameras for efficient astrophotography performance. Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings with a protective silicon dioxide (quartz) overcoat.

To optimize contrast and avoid off-axis light intrusion near the front of the telescope, the dual-speed 2 inch linear-bearing design Crayford focuser has been installed a full 7 inch back from the front of the compact 22.5 inch long reflector optical tube. For consistent results every night, an Orion-exclusive steel reinforcing plate underneath the focuser eliminates flexure, even with heavy cameras and other imaging gear attached. As with any fast Newtonian reflector telescope, an optional coma corrector is recommended to eliminate inherent coma for optimized imaging performance.
