Astro-Tech 8" f/4 Imaging Newtonian Optical Tube - USED

A review of three Astro-Tech astrographs (the AT6RC and AT8RC Ritchey-Chrétiens, as well as this AT8IN Imaging Newtonian) in the December 2009 issue of Sky & Telescope said "While all three of the Astro-Tech scopes represent excellent value, the AT8IN, with its 8-inch aperture and $399 price tag, wins the biggest-bang-for-the-buck award . . . there's a quality to this scope that seems contradictory to its relatively low cost."

This Astro-Tech Imaging Newtonian optical tube has:

  • very fast f/4 focal ratio 8" Newtonian reflector optics
  • contrast-enhancing extended tube length with 15 internal baffles
  • built-in cooling fan for faster primary mirror cooldown
  • 2" dual-speed Crayford focuser with 2" and 1.25" compression ring accessory adapters
  • 8 x 50mm finderscope in a quick-release bracket
  • dual split hinged mounting rings
