About Explore Air-Spaced Doublet Refractors

The Explore Scientific AR Series telescopes are classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractors with a superior-class optical figure. Whether you choose the AR102 (4"), AR127 (5") or AR152 (6") model, 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 finderscope 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…


  • Available in 102mm, 127mm & 152mm apertures. All models are f/6.5.
  • 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° 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.
  • All Explore Scientific products come with a STAR Extended-Life-of-the-Product Warranty. Upon registration, this product will be under warranty for as long as it is manufactured, plus five years

     AR Optics in Adjustable Cell

    It's all about the optics! The Crown & Flint optical elements used in the AR Doublet Series telescopes are fully multi-coated to eliminate light scatter and maintain image contrast. We precision collimate every Explore Scientific telescope at our factory to give optimum performance. Although you may never need to adjust optical alignment, the AR Series allows for collimating the lens set should the telescope ever require.  As a privilege of ownership, those who wish to obtain a copy of their Air-Spaced Doublet Series interferometric data can request it 90 days after registering the warranty of your telescope by contacting our Customer Service Department..

  • Explore Scientific EMD Coatings

     Explore EMD™ Coatings

     EMD (Enhanced Multi-layer Deposition) Coatings eliminates light scatter and maintains high image contrast. This proprietary coating is applied to all Explore Scientific lenses in multiple layers for added durability.

     Contrast is further enhanced with multiple knife-edge baffles in the optical tube that mask and deflect unwanted stray light.

    Deluxe Two-Speed Focuser


    The Explore Scientific AR102, AR127, and AR152 Air-Spaced Doublet Refractors include a high quality precision 2" dual-speed Crayford-style focuser with 10:1 micro focus and tension adjustment. The ability to adjust and lock the tension on the draw tube is helpful when you change the weight of the load.


    You will appreciate the smooth movement, the large course and fine focusing knobs, and the graduated scale imprinted on the draw tube. A 1.25" compression ring eyepiece adapter is included.

  • The Critical Element: Optics

     Designing and manufacturing optics is at the heart of what we do. Explore Scientific designers and optical craftspeople constantly strive to produce optical tools that will deliver the precision and dependability that explorers of the Universe deserve, regardless of their level of expertise.   Producing optics of this caliber requires a solid design, careful fabrication, and multiple tests throughout the manufacturing process, but it also takes a dogged determination to keep perfecting our processes and skills so that our products keep getting better and better. To further insure your faith in Explore Scientific products, we back all of our telescopes with the Explore STAR Transferrable, Extended Life of the Product Warranty, so you can keep exploring!
