Looking for a great telescope at a great price? Look no further than the Explore Scientific AR127 telescope!
Supporting UNESCO in Space Education!
The classic air-spaced, crown-and-flint, 127mm (5-inch) 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. Which is why UNESCO chose the AR127 to use in its programs to bring science to the educational systems to schools in developing countries.
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 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 transferable Five Year USA Limited Warranty from Explore Scientific.

At the UNESCO World Headquarters in Paris. Scott Roberts from Explore Scientific signs a special cooperation agreement with Walter Erdelen, UNESCO's Assistant Director General for Science, and Yolanda Berenguer UNESCO's Space Education Programme Coordinator to produce the UNESCO - Explore Scientific Air-Spaced Doublet AR Series refracting telescopes for Astronomy and Space Science outreach in developing countries.

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 Two-Speed Focuser
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 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 127 fits on many popular equatorial and Altaz 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.
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-inch Diagonal Mirror
The Two-inch Mirror Diagonal includes a 1.25-inch eyepiece holder adapter, so that you can use the full range of eyepieces and Barlow lenses.

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