Explore Scientific 152 mm Achromatic Refractor OTA
This 6" Doublet Refractor, by Explore Scientific, features air-spaced doublet optics produced from flint and crown glass to give you astonishing celestial views. You will be astounded by the marvelous views in your scope of the Moon, planets, and double stars. The telescope package includes many high-tech accessories to make your long nights observing a breeze. Accessories include a 2" dual-speed focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 non-illuminated straight-thru finderscope and quick release bracket, and a cradle ring assembly with a Vixen-style dovetail mount. All you need is a few eyepieces and an alt-azimuth or equatorial mount and you are ready to explore the skies!
The Explore Scientific Air-Spaced Doublet AR Series telescopes include a precision 2-inch two-speed focuser 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 AR Series, a two-speed Crayford-style precision focuser with tension adjustment and a lock, to obtain and hold perfect focus. We think you'll agree that such precision is worth it.
The Two-Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror. 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 48 mm filters into the barrel.
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 of your scope.
