Please Note

Orion has made the difficult decision to close our warehouse facility in the Netherlands. With the continuing supply chain/logistics challenges and slowness in the economy we have found that it is not economically feasible to maintain operations in the UK and Europe.

We have therefore stopped taking orders on this website. We apologize for any inconvenience.

We will continue to have Orion dealers in Europe to meet the needs of Orion consumers. We will also continue to honor the 30-Day product return period as well as honoring the Orion warranty for purchases made in the UK and Europe.

Our US-based Customer Service Representatives are here to help. Contact them via email at support@telescope.com or in the United Kingdom, via phone at 0-800-041-8146 (Monday-Friday between the hours of 1300 and 2400 GMT).

Our 6" aperture imaging reflector is loaded with 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" 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. (5.76kg), so it doesn't require a huge mount to support it.

The rolled-steel Newtonian Reflector optical tube's 6"-aperture parabolic primary mirror measures 610mm in focal length, making the optically fast f/4 Astrograph a perfect choice for going after wide-field images of distant deep-space objects. Since the primary mirror is made of thermally stable B270 glass, it acclimates to ambient temperature more quickly than standard reflector telescopes. An oversized, 63mm minor axis secondary mirror provides excellent field illumination for DSLR and CCD cameras. Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings to optimize contrast with a protective silicon dioxide (quartz) overcoat. 

The 6" f/4 Newtonian Astrograph Reflector features a precise, 2" (50.8mm) dual-speed (10:1) linear-bearing Crayford focuser which lies 7" (17.8cm) back from the front of the 22.5" (57.15cm) long optical tube. This recessed focuser position helps maximize contrast by blocking stray off-axis light for high-resolution performance. The super-steady linear-bearing Crayford focuser design will hold heavy imaging payloads without slippage. 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. A 2" (50.8mm) compression ring collar and 1.25" (31.75mm) compression adapter keep inserted cameras and accessories secure without scratching. 

Of course, the 6" f/4 Newtonian Astrograph can also be used for spectacular visual observations of deep-sky and solar system based celestial objects. An included 2" diameter extension tube adds 1.38" (35mm) of length to the focuser for visual use. The reflector's 6" (150mm) aperture and fast focal ratio will amaze you with high-contrast views of the cosmos.

A pair of hinged, die-cast aluminum tube rings with felt lining are included, which each have flat bosses on the top and bottom featuring M6 threaded sockets for easy attachment of the included Vixen-style mounting bar and additional imaging accessories. An 8x50 straight crosshair finder scope with dovetail bracket and snap-on dust cap are also included.

As with any fast Newtonian reflector telescope, an optional coma corrector is recommended to eliminate inherent coma for optimized imaging performance.
