The Explore Scientific AR127 f/6.5 Achromatic Refractor delivers superb optical performance in a value-packed, rugged design—perfect for both serious observers and public outreach events. Built around a 127mm air-spaced crown-and-flint doublet, this classic achromatic refractor is engineered for sharp, bright views with minimal chromatic aberration at a fraction of the cost of an apochromatic scope.
With a short focal ratio of f/6.5, the AR127 excels in wide-field observing, revealing star clusters, nebulae, and sweeping lunar vistas with crisp resolution and high contrast. It's equally well-suited for detailed planetary and lunar views, especially when paired with quality eyepieces and filters.
The robust mechanical build includes a 2" dual-speed Crayford focuser, 99% dielectric diagonal, and an 8x50 finder scope—making this telescope ready for any visual astronomy challenge straight out of the box. A Vixen-style dovetail and cradle rings make it easy to mount on most equatorial or alt-az setups.
Whether you're an experienced astronomer looking for a capable grab-and-go refractor or an educator hosting public nights, the AR127 combines excellent optics with reliable hardware—and stunning performance in its class.
