The Explore Scientific AR Air-Spaced Doublet Series telescopes are classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractors with a superior-class optical figure.,

Designed to bring you the best viewing experience, the Explore Scientific AR Series telescopes come with heavy-duty, high-quality components, including a 2-inch Two-Speed Crayford Focuser with Compression, a 99% Reflective Dielectric-Coated 2-inch Diagonal Mirror with 1.25-inch Eyepiece Adapter, an 8X50 non-illuminated straight-thru finderscope, and quick release bracket, and a cradle ring assembly with 45mm wide dovetail plate (Vixen-style).

  • Crayford focusers use a toothless friction system that allows for super-fine precision focusing without backlash
  • Large 2" drawtube prevents vignetting when using wide-field eyepieces for viewing, or large imaging sensors for astrophotography
  • Compatible with any alt-az or equatorial mount with a Vixen-style saddle
  • Integrated carry handle on cradle-ring assembly
