The Vixen Porta II A80Mf is for you if…

• You need an upgrade from a basic beginner scope – Moving beyond a small 60mm refractor or tabletop scope? The A80Mf delivers superior optics and a stable mount without the complexity of computerized setups.
• You want a manual telescope without the hassle of polar alignment – Unlike equatorial mounts, the PORTA II’s alt-azimuth movement lets you point and track objects easily—perfect for spontaneous stargazing.
• You want a telescope for both celestial and terrestrial use – The included erect-image diagonal lets you observe landscapes, wildlife, and the Moon in a natural orientation—no upside-down images.
• You need a portable telescope – The lightweight, detachable tripod and mount head allow for easy transport—no complex breakdown required.

Investing in a telescope isn’t just about the equipment—it’s about what you can see. Whether you're a serious amateur astronomer, a science-loving parent, or an outdoor enthusiast, the Vixen Porta II A80Mf delivers an experience beyond ordinary stargazing. Its high-quality optics, intuitive manual control, and lightweight portability make it perfect for those who want crystal-clear views without complicated electronics.

Many beginner telescopes hold you back, but the A80Mf is designed to grow with you. The 80mm achromatic lens and fully multi-coated optics deliver sharp, high-contrast views of planets, the Moon, and deep-sky objects—without the distracting color distortion found in lower-quality refractors.

With a 910mm focal length and f/11.4 focal ratio, this telescope is built for detailed planetary and lunar observation. Whether you’re viewing Saturn’s rings, Jupiter’s cloud bands, or the rugged surface of the Moon, the A80Mf delivers striking clarity.

Additionally, with a resolution of 1.45 arc seconds and a limiting magnitude of 11.3, this telescope allows you to resolve fine planetary details and observe deep-sky objects that are 150 times fainter than the human eye can detect under dark skies.

The PORTA II mount makes tracking objects effortless. Its smooth slow-motion controls and friction-based slip clutch allow for precise movement without constant adjustments. No motors, no batteries—just hands-on, intuitive stargazing. The slow-motion control handles adjust in 45-degree increments, allowing you to find the most comfortable hand position while tracking celestial objects.

Portability matters, and the A80Mf is designed for adventure. Whether you're setting up in your backyard, heading to a dark-sky location, or using it for daytime landscape viewing, it’s light enough to carry yet stable enough for clear, steady views. The quick-release dovetail system allows for easy optical tube swaps, letting you customize your setup over time.

If you're looking for a high-performance telescope that won't hold you back, the Vixen Porta II A80Mf is the perfect choice.
