70XL-SD Binocular Telescope

NOTE – The supplied 14mm eyepieces are now all-black, instead of black with red trim. We’ll update pictures soon, but in the meantime, you can look at images from our Tactical Edition binocular telescopes to see the updated eyepieces.

A True Apochromatic Experience in a Portable Form

The Oberwerk 70XL-SD is the most compact member of the XL Series, bringing true apochromatic performance to a remarkably portable binocular telescope. Featuring 70mm FCD100 super-low dispersion (SD) apochromatic objectives, 24mm clear-aperture prisms, and a lightweight magnesium-alloy body that’s both waterproof and nitrogen-filled, the 70XL-SD delivers bright, sharp, and color-accurate images far beyond what’s typical for its size. Despite its compact design, it’s capable of 56× magnification with outstanding clarity and virtually zero chromatic aberration.

Engineered for Versatility and Ease of Use

The magnesium-alloy chassis keeps total weight low without sacrificing strength or precision. Extendable glare shields protect the objectives and enhance contrast, while the Picatinny rail handle allows direct mounting of red-dot finders, laser pointers, or other accessories for easy targeting. The ultra-wide 50–80mm IPD range ensures that observers of all ages — even small children — can enjoy a perfectly aligned, comfortable two-eyed view.

Finished in Luna Pearl White with red-anodized trim, the 70XL-SD is as stylish as it is capable — a perfect blend of performance and portability.

Complete Observation Kit

Each binocular telescope includes premium 8-element, 14mm (28×) 70° AFOV eyepieces, providing immersive, wide-field views with exceptional edge sharpness. Optional 22mm (18×) and 7mm (56×) eyepiece pairs extend the magnification range for both expansive deep-sky vistas and high-power lunar or planetary observing. An exclusive heavy-duty aluminum-frame case is included for safe transport and storage.

Hand-Tuned and Certified

Every 70XL-SD is individually collimated, tested, and tuned by hand, with alignment certified to 98× (step <12 arcseconds). Backed by a 5-year Limited Warranty, it delivers Oberwerk’s hallmark combination of precision optics, robust engineering, and lasting quality.
