The latest addition to the Air-Spaced Doublet AR Series is the very portable, grab-and-go Explore Scientific AR102 f/6.5 Air-Spaced Doublet AR Series Achromat Refractor Telescope! Like its two larger brothers, the AR127, and the AR152, these are classic air-spaced, crown-and-flint, doublet achromatic refractors with superior-class optical figure, 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 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 rigors of 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.

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. Explore precision collimates every Explore Scientific Telescope at their 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 Doublet AR 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. On those prestine nights of steady seeing, Saturn''s Rings can forever affect the hearts and minds of almost anyone who lays eyes on them. It''s nights like these that astronomers like to set up their refractors and push the magnification to the limits, not only to see the magnificence of the planet at greater scale but to really test the optical and mechanical quality of the Explore Scientific AR102 f/6.5 Air-Spaced Doublet AR Series Achromat Refractor Telescope.

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 Explore included as standard equipment, on all Explore Scientific AR Series, 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 Explore Scientific AR102 f/6.5 Air-Spaced Doublet AR Series Achromat Refractor Telescope fits on many popular equatorial and Altaz mounts, including mounts supplied by Explore Scientific, Celestron, Vixen, and others. Instead of using a cast metal part, Explore Scientific''s Universal Mounting Plate is made from extruded aluminum for added strength, it is afterall what secures your telescope to the mount. Explore also includes adjustment screws and locking bolts to allow adjustments to position the angle of the telescope when it is placed on its mount, an important feature when using an equatorial mount.

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. 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 precision 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. The purpose of a diagonal is to securely hold your eyepiece in your Explore Scientific AR102 f/6.5 Air-Spaced Doublet AR Series Achromat Refractor Telescopeand to give you a comfortable viewing angle. Provided as standard equipment, Explore Scientific''s Two Inch Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment.

8x50 Finder Scope

The Explore Scientific 8x50 Finder Scope provides a true field of view of 6 degrees. 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.

About the Explore Scientific Twilight I Mount

The Twilight I is a light-to-medium-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors, such as the ES AR102 or Carbon Fiber 102mm, and of course, the 80mm. Light weight, fast Newtonians will also match up nicely with the Explore Twilight I mount.

The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45ᄚ angle, or you can point it straight up for viewing at the zenith. Slow motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. A small wrench is included with this package, and is stored in the fork arm and held in place with a magnet. If you need to make quick adjustments to your mount, it is a snap to access the wrench and then store it safely away when done. It is a small thing, but an adjustment wrench is one less tool you will need to remember to bring with you on observing sessions!

The chrome-plated steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum.
