Orion 6" Newtonian Imaging OTA

Here's a Serious Astrophoto Reflector at a Great Price!. See The Review In The April 2008 Issue Of Sky & Telescope.

Step up to serious astrophotography with this high quality, heavy duty wide-field reflector Compares head-to-head with many high-end imaging refractors but at a fraction of the price Optimized to fully illuminate the image chip in Orion StarShoot CCD cameras and most digital SLRs Beefy 2" Crayford-style focuser accepts 1.25" accessories and easily supports heavy cameras

If your astrophoto aspirations go beyond our 4.5" Imaging Reflector, step up to this 6" model. Its performance compares head-to-head with many high-end refractors, but at a fraction of the price.

With its large 6" (150mm) parabolic mirror, this compact f/5 astrograph is optimized to fully illuminate the imaging chip of Orion StarShoot CCD cameras and most digital SLRs, rendering exquisite detail even with short exposures. Added tube length in front of the secondary mirror blocks glare for improved contrast. Images are virtually coma free and, of course, there?s no chromatic aberration.

The focuser is a low-profile, 2" Crayford-style design made of machined, anodized aluminum and it has coarse and fine (11:1) focus controls. It comes with a 1.25" compression ring adapter and a dovetail base for an Orion finder scope.

Put the 6" Imaging Reflector on any Orion mount and you?ll have one awesome telescope for imaging! And when you want a break from that, just pop in an eyepiece for brow-raising visual adventures.
