Astronomy Magazine, November 2010
“I found this telescope a total pleasure to use. The precise mechanical operation of its focuser made all the difference in the world. Sharp arcsecond-sized star images filled the field of view on successive 5-minute exposures with an absolutely stunning amount of nebulosity visible on my DSLR’s screen... Orion’s 8-inch f/4.0 Newtonian Astrograph Reflector allows budget-minded sky shooters access to a new level of high-quality imaging.”
In keeping with our philosophy of offering great astrophotographic gear at affordable prices, we’re pleased to offer our 8" f/4.0 Newtonian Astrograph Reflector. For wide field, deep-space imaging performance, this telescope has few rivals. Its big 8" aperture and fast f/4.0 focal ratio allow the capture of faint galaxies and nebulas with short photographic exposure times — and for a fraction of the price that a premium "apo" refractor of even half its size would cost!
Our Orion 8" f/4.0 Newtonian Astrograph Reflector is perfect for beginning and intermediate star shooters, and a great second telescope for more advanced imagers who want more portability, without sacrificing features and quality. That means bright, detailed images for APS-C sized CCD or DSLR cameras. As with any fast Newtonian reflector, an optional coma corrector is recommended to achieve the sharpest images. With an optional eyepiece, this telescope doubles as a fine visual instrument for scanning solar system and deep-space wonders.
Only 16 lbs. and just 28" long, this instrument is easily supported on a mid-sized mount. The 200mm-aperture parabolic primary mirror is made from high-quality BK-7 optical glass. Enhanced aluminum mirror coatings with greater than 91% reflectivity deliver more light to the focuser. A cooling accelerator fan is included, mounted on the back of the primary mirror cell for rapid equilibration to ambient temperature.
We outfitted the 8" f/4.0 Astrograph with a modified, all-machined 2" dual-speed Crayford focuser that incorporates a special linear-track bearing. This advanced focuser design provides superior camera support and eliminates the drawtube flexure inherent in many standard Crayford focusers. The dual-speed feature allows both coarse and very fine (10:1) focusing precision. Standard accessories include a pair of hinged tube rings and an 8x50 finder scope.
Great telescopes for astrophotography don’t have to cost thousands! In fact, you can own an 8" imaging-optimized Newtonian reflector for well under $500! Get the Orion 8" f/4.0 Newtonian Astrograph Reflector today.
