DESCRIPTION

Used Explore Scientific 152mm f/6.5 Achromatic Refractor with Finder Scope - SOLD

The Explore Scientific AR152 (six inch) f/6.5 Air-Spaced Doublet Achromat Refractor, with its larger aperture optics gathers 44% more light over the AR127 (five-inch) model, providing much brighter images and higher resolution. The 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 has standard hardware which includes a precision 10:1 two-speed focuser, a 2-inch diagonal, and an 8x50 finder scope.

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.

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 refractor telescopes 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. Now included as standard equipment on all Explore Scientific AR Series telescopes is 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.

The Universal Adjustable Mounting Plate of the AR 152 fits on many popular equatorial and Alt-Az mounts, including mounts supplied by Explore Scientific, Vixen, and Meade LXD55/75.

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. Also included are 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.

The Two Inch Dielectric Diagonal includes a 1.25" 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 alignment.

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 nebulae can be detected for precise aiming.

*The front objective can be custom focused to provide a sharp image every time.
