Explore Scientific AR102 refractor telescope f/6.5 with 8X50 Finder, 99% Two -inch Diagonal, DAR102065-01
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
AR Series. 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 10:1 two-speed focuser, a 2-inch diagonal, an 8x50
finder scope, and a case. You can be confident that the quality and
construction of these telescopes will allow heavy use for many years and
are backed with a transferrable Five Year USA Limited 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.
Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light.
Deluxe 10:1 Two-Speed Focuser
The Explore Scientific Air-Spaced Doublet AR Series telescopes include a
precision 2-inch ten-to-one, two-speed as standard equipment. The
eyepiece holder uses a compression ring to prevent the eyepiece or
camera barrel from scoring.
On those pristine 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 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 we included as standard equipment, on all
Explore Scientific AR Series, a ten-to-one, 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, Vixen, and Meade.
Instead of using a cast metal part, Explore Scientific's Universal
Mounting Plate is made from extruded aluminum for added strength, it is
after all what secures your telescope to the mount. We also include
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.
2" Diagonal Mirror
The Two Inch Dielectric Diagonal includes a 2" eyepiece holder adapter.
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 Diagonal
incorporates a light-weight, one-piece diagonal body that securely
cradles the precision polished diagonal flat mirror, insuring precision
8x50 Finder Scope
The Explore Scientific 8x50 Finder Scope provides a true field of view
of 6 degree. Its coated optics provide a bright high-resolution image so
that many faint stars and nebulosity can be detected for precise
The front objective can be custom focused to provide a sharp image every time.
