Explore Scientific AR127 f/6.5 Air-Spaced Doublet AR Series™ Achromat Refractor Telescope

Explore Scientific AR127 f/6.5 Air-Spaced Doublet AR Series™ Achromat Refractor Telescope

The classic air-spaced, crown-and-flint, doublet achromatic refractor is reborn with the aim to produce superior-class optical figure in a short (f/6.5) focal length design with Explore Scientific Air-Spaced Doublet ARSeries. These optics are an extreme value, produce stunning images of deep sky objects, double stars, planets, and the moon that are a small fraction of the price of comparable aperture apochromat refractors. Finally one can own a diffraction-limited high quality refractor for a relatively modest investment.

Designed to handle the rigorsof public star parties and educational outreach, the Explore Scientific AR Series has standard hardware which includes a precision two-speed focuser, a 99% Reflective 2-inch Diagonal Mirror, and an 8x50 Finder Scope. You can be confident that the quality and construction of these telescopes will allow heavy use for many years and are backed with the Explore STAR Transferrable Extended Life of the Product Warranty.

It's All About the Optics!
The optics in their collimatable lens cell 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 it.

Deluxe Two-Speed Focuser
The Explore Scientific Air-Spaced DoubletAR Series telescopes include a precision 2-inch two-speed as standard equipment. The eyepiece holder uses a compression ring to prevent the eyepiece or camera barrel from scoring.

Many telescopes are only supplied with a standard single-speed focuser, you will find that a tiny nudge will throw out focus and turn your night into one of frustration.

So we included as standard equipment, on all Explore Scientific ARSeries, a two-speed Crayford-style precision focuser with tension adjustment and lock to obtain and hold perfect focus. We think you'll agree that such precision is worth it.

Universal Mounting Plate
The Universal Adjustable Mounting Plate of the AR 102 fits on many popular equatorial and Altaz mounts, including mounts supplied by Explore Scientific, Celestron, Vixen, and others.

Viewing Comfort and the Preservation of Precious Light
The Two-Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror.

8x50 Finder Scope
The Explore Scientific 8x50 Finder Scope provides a true field of view of 6°. Its coated optics provide a bright high-resolution image so that many faint stars and nebulosity can be detected for precise aiming.

The front objective can be custom focused to provide a sharp image every time.
