What people like
The Explore Scientific AR102 Air-Spaced Doublet Refractor is a popular 4-inch (102mm) achromatic telescope designed to offer excellent value and performance for visual astronomy. With a fast f/6.5 focal ratio (663mm focal length), it delivers crisp, high-contrast images of the Moon, planets, double stars, and brighter deep-sky objects. This "DEMO" model is an Optical Tube Assembly (OTA) only, meaning it typically includes the telescope tube, a 2-inch two-speed Crayford focuser, cradle rings with a Vixen-style dovetail, but generally does not include a finder scope or diagonal, requiring separate purchases for a complete setup.
Pros
- Good Optical Performance for an Achromat: Utilizes an air-spaced crown-and-flint doublet lens with multi-coatings for sharp images and good contrast, especially for its price point.
- Robust Build Quality: Features an all-metal construction and a solid 2-inch two-speed Crayford focuser with compression rings, offering a durable and precise feel.
- Portable "Grab-and-Go" Size: Its relatively short tube length (around 648mm / 25.5") and weight (around 5.2 kg / 11.5 lbs) make it manageable for quick setups and transport.
- Versatile for Visual Observing: Capable of providing pleasing views of a wide range of celestial objects, suitable for both beginners and more experienced visual astronomers.
Description
The Explore Scientific AR Air-Spaced Doublet Series telescopes are classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractors with a superior-class optical figure. Whether you choose the AR102 (4"), AR127 (5") or AR152 (6") 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 apochromatic refractor, and you'll love the light weight of this instrument at only 11.5 lbs.
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-inch Two-Speed Crayford Focuser with Compression , a 99% Reflective Dielectric-Coated 2-inch Diagonal Mirror with 1.25-inch Eyepiece Adapter, the Explore Scientific Hybrid Finder Scope Base installed with an 8X50 non-illuminated straight-through finderscope and quick release bracket, and a cradle ring assembly with 45mm wide dovetail plate (Vixen style). Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you’ll be ready to discover the Universe!
