$749.99

The AR152 (six-inch), with its larger aperture optics gathers 44% more light over the AR127 (five-inch) model, providing much brighter images and higher resolution. Our goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field large aperture refractor. Images of deep sky objects are stunning at low powers. At high power the moon and the planets are revealed in sharp, high contrast.

 

Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series telescopes come with heavy-duty, high quality components, including a 2" dual-speed Crayford-style focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 finderscope and quick release bracket, and a cradle ring assembly with Vixen-style dovetail mount. Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you'll be ready to discover the Universe!

It's All About the Optics!
Fully Multi-Coated 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 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. Perfect focus is easily achieved with the Explore Scientific Two-Speed Focuser  


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 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 Mounting Plate of the AR Series Telescopes The Universal Adjustable Mounting Plate of the AR 152 fits on many popular equatorial and Altaz mounts, including mounts supplied by Explore Scientific, Vixen, Meade 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. 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.

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. Dielectric-Coated 2-inch Precision Polished Diagonal

 

 

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.
