The classic air-spaced, crown-and-flint, 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. Whether you choose the AR127 model, you will be impressed by the stunning images revealed to you at the eyepiece, and all at a small fraction of the price you'd 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 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!
AR127 Air-Spaced Doublet Refractor Highlights
- 127mm f/6.5 design.
-The tube assembly is constructed from aluminum and stainless steel and painted gloss white.
-Classic Crown & Flin Air-Spaced Doublet achromat optics.
-Research-grade, diffraction limited surfaces.
-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.
-Come with a heavy-duty 2" two-speed focuser.
-The light-weight 2" diagonal has 99% dielectric coatings for high contrast, bright images. A 1.25" compression ring adapter is included.
-Includes an 8x50 straight-thru finderscope with a wide 6° field of view, with front objective focus.
-To attach your Explore Scientific Air-Spaced Doublet telescope to a variety of mounts, we have included an extra strong extruded aluminum Cradle Ring Assembly and Universal Adjustable Mounting Plate. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
Each AR127 is serial numbered and if registered within 60 days is protected with the Explore STAR Lifetime Transferrable Warranty.
