The Explore Scientific AR102 offers advanced features such as a dual speed focuser and is a great value in a four-inch refractor. This is a classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractor with a superior-class optical figure. You will be impressed by the stunning images revealed to you at the eyepiece, and all at a small fraction of the price you'd pay for a comparably sized apochromat refractor.

Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series telescopes come with heavy-duty, high quality components, including a 2" dual-speed Crayford-style focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 finder scope and quick release bracket, and a cradle ring assembly with Vixen-style dovetail mount. Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you'll be ready to discover the Universe!

Explore Air-Spaced Doublet Refractor Highlights

  • Reasonably compact f/6.5 optics.
  • The tube assembly is constructed from aluminum and stainless steel and painted gloss white.
  • Classic Air-Spaced Doublet achromat optics made with Crown & Flint glass
  • Research-grade, diffraction limited optics.
  • Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter.
  • While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending off to the factory is an option, but is not required.
  • All models come with a heavy-duty 2" Crayford-style two-speed focuser.
  • The heavy-duty 2" diagonal has 99% dielectric coatings for high contrast, bright images. A 1.25" compression ring adapter is included.
  • Includes an 8x50 straight-thru finderscope with a wide 6 degree field of view. The front objective is focusable.
  • To attach your Explore Scientific Air-Spaced Doublet telescope to a variety of mounts, we have included an extra strong extruded aluminum Cradle Ring Assembly and Universal Adjustable Mounting Plate. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
