The Explore Scientific AR152 is a large refractor that is sure to delight by providing bright images of deep space objects.
The Explore Scientific AR152 is a classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractor with a superior-class optical figure. Large aperture refractors reveal deep space objects in ways that other telescopes simply cannot. The relatively short 988mm focal length of this instrument allows for amazing wide field views in excess of two degrees, all with pinpoint stars across the entire field. You will be impressed by the stunning images revealed to you at the eyepiece; most people don't event want to think about what you would pay for a comparably sized apochromat refractor.
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 finder scope 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!
The tube assembly is constructed from aluminum and stainless steel and painted gloss white.
Classic Air-Spaced Doublet achromatic optics made with Crown & Flint glass
Research-grade, diffraction limited optics.
Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter.
While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending off to the factory is an option, but is not required.
All models come with a heavy-duty 2" Crayford-style two-speed focuser.
The heavy-duty 2" diagonal has 99% dielectric coatings for high contrast, bright images.
Includes an 8x50 straight-thru finderscope with a wide 6 degree field of view. The front objective is focusable.
Orion AstroView Equatorial Mount
Smooth-moving, sturdy AstroView EQ. It has enclosed worm gears, azimuth adjustment, and dual slow-motion controls. Hinged center brace adds stability to the all-aluminum adjustable tripod. Includes polar alignment scope and high-walled accessory tray. Weighs 27.5 lbs.
