Product Description

Charlie Bates Solar EndorcementThe Latest Addition to the VIXEN OPTICS  Air-Spaced Doublet AR Series of Very Portable Refractors (VPR) is a grab-and-go 102mm Telescope!  Like its two larger brothers, the AR127, and  AR152, this is a classic air-spaced, crown-and-flint, doublet achromatic refractor with superior-class optical glass, in a short f/6.5 focal length design. These optics are an extreme value, produce stunning images of deep sky objects, double stars, planets, and the moon at are a  fraction of the price of comparable aperture apochromat refractors. Finally one can own a diffraction-limited high quality refractor for a relatively modest investment.

The Optics in this instrument are fully Multi-Coated to eliminate light scatter and maintain image contrast.  Every Explore Scientific Telescope is precision Collimated at the factory to give optimum, accurate performance.  Although the user may never need to adjust optical alignment, the AR Series allows for in-the-field collimation of the Primary/Secondary lens set should the telescope ever require it. 

Designed to handle the rigors of every night use, the Explore Scientific AR Series has standard hardware which includes a Precision 2 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.

The Two-Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror.The purpose of a diagonal is to securely hold your eyepiece and to give you a comfortable viewing angle.Provided as standard equipment, Explore Scientific's Two Inch Dielectric Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precise alignment. Ultra-high reflective coatings (99% reflective) composed of multiple thin layers of dielectric material delivers maximum light output.
Both 2" and 1.25" eyepiece holders use compression rings instead of a simple set-screw to more securely hold your valued eyepiece (or imaging device) and to minimize scoring of eyepiece barrels. You can thread standard 48mm filters into the barrel.

Explore Scientific Air-Spaced Doublet AR Series telescopes include a precision Crayford style 2-inch two-speed Rack and Pinion Focuser as standard equipment. This ultra-precise focuser also has tension adjustment and lock feature to obtain and hold perfect focus. Many telescopes are only supplied with a standard single-speed focuser, and users find that even a tiny nudge will throw out focus.

And there's more!  The standard 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.

The ultimate "grab-n-go" companion for most portable telescopes, the new TwiLight I Alt-az Mount has geared slow motions with flexible cable controls for fine altitude and azimuth adjustments.  Its sturdy metal, continuously adjustable-height tripod will withstand years of rugged use. This mount, with it's adjustable angle head, provides a lighter and more versatile alternative to VIXEN's TwiLight II mount. It has all the smoothness and versatility of its dual head cousin in just one head, making it smaller, lighter, and providing users with the mobility and ease that you desire. The TwiLight I is a perfect choice for all of your viewing needs and it is made with all the special care and craftsmanship of all Explore Scientific products.
