Explore Scientific AR Series 127mm f/6.5 Doublet Refractor Telescope

The Explore Scientific air-spaced doublet refractor is the perfect choice for both novice and experienced astronomers.

The AR127 is a classic air-spaced, crown-and-flint, doublet achromat aimed towards bringing you stunning and sharp images of your favorite celestial objects.

Unlike a traditional rack-and-pinion focuser, a Crayford-style uses a steel rod held tightly against the focus tube. This toothless friction system eliminates backlash and enables ultra-fine precision focusing.


  • Achromatic lenses eliminate chromatic and spherical aberrations for true color rendition and without distortion across the entire field of view
  • Comes with an 8x50 non-illuminated finderscope with quick-release bracket
  • Compatible with any alt-az or equatorial mount with a Vixen-style saddle
  • Cradle-ring assembly for plate allows the scope orientation to be changed based on mount configuration
