Description
Featuring a 70mm (2.76 inches) aperture and a balanced f/10 focal ratio, the Omegon AC 70/700 AZ-2 Telescope manual refractor system delivers high-contrast views of planetary targets. Designed in Germany with a 700mm focal length, this achromatic telescope achieves 1.66 arcsecond Dawes resolving power and reaches down to a limiting visual magnitude of 11.0 for amateur astronomers.
The Omegon AC 70/700 AZ-2 Telescope incorporates a two-element air-spaced crown and flint glass doublet objective with multi-coated anti-reflective layers on all air-to-glass surfaces. Its rigid aluminum tube construction features internal matte-black anti-reflection baffles to suppress stray light. Supported by an AZ-2 altazimuth fork mount with a slow-motion altitude adjustment rod, the full assembly weighs 3.80 kg (8.38 lbs), providing dependable stability for lunar observation.
Key Features of Omegon AC 70/700 AZ-2 Telescope

Balanced f/10 Achromatic Refractor Optics
The 70mm multi-coated doublet objective utilizes a 700mm focal length to control chromatic fringing effectively. Featuring an unobstructed optical profile (0.0% obstruction), this Omegon refractor delivers sharp, high-contrast imagery across magnifications ranging from 10x up to 140x.
AZ-2 Altazimuth Fork Mount & Slow-Motion Altitude Rod
Centering lunar craters and planetary disks requires precise vertical control. The Omegon AC 70/700 AZ-2 features an altazimuth fork mount equipped with a slow-motion altitude fine adjustment rod for smooth framing updates. Paired with two Super eyepieces and a 2x Barlow lens, it offers adaptable magnification options for stargazers.
- AZ-2 fork mount with slow-motion altitude rod on an adjustable aluminum tripod
- Included Super 20mm and Super 10mm eyepieces with 2x Barlow lens element
- 1.25-inch 90-degree star diagonal mirror for comfortable visual ergonomics
Omegon AC 70/700 AZ-2 Warranty
The Omegon AC 70/700 AZ-2 Telescope is backed by a 2-year limited warranty covering parts and craftsmanship defects. The complete package contains the 70mm refractor OTA, AZ-2 fork mount, adjustable tripod with accessory tray, slow-motion altitude rod, red dot finder, 90-degree star diagonal, two eyepieces, and a 2x Barlow lens.
