The Vixen Porta II A80Mf is for you if…

• You’ve outgrown budget telescopes and want professional-level optics without professional-level complexity.
• You prefer hands-on observing over digital interfaces and want full control of your viewing experience.
• You value smooth tracking at high magnification, especially for planetary viewing—without frustrating drift or vibration.
• You want a telescope that’s portable enough for travel, yet stable enough to deliver clean, focused images even in breezy conditions.
  
• You care about engineering quality and build reputation, and know Vixen is a brand trusted by experienced astronomers worldwide.

You’re not here for gimmicks. You’re here to see the rings of Saturn with your own eyes. To watch the craters of the Moon cast shadows at sunrise. The Vixen Porta II A80Mf is designed for observers like you—those who care about what they see and how they get there.

This isn't a toy telescope, nor is it a complicated astrophotography rig you’ll spend hours trying to align. It's a serious, well-built instrument that lets you point, track, and observe with absolute control. No motors. No menus. Just smooth, deliberate motion and optical clarity that brings distant worlds into focus.

Every detail is intentional. The 80mm multi-coated achromatic lens delivers sharp, high-contrast views with minimal chromatic aberration. With a long focal length of 910mm and a focal ratio of f/11.4, it’s especially powerful for lunar and planetary detail. You’ll see Jupiter’s cloud bands, Saturn’s rings, and deep lunar craters—thanks in part to its impressive angular resolution of 1.45 arc seconds, which allows it to resolve fine details many beginner scopes miss.

This scope doesn’t just let you see more—it helps you see deeper. With a visual limiting magnitude of 11.3 and a light-gathering power 131x that of the unaided eye, you’ll also be able to explore bright nebulae, open star clusters, and galaxies under dark skies.

Out of the box, it comes ready to perform. The two included Plössl eyepieces (20mm and 6.3mm) provide 46x and 144x magnification, giving you both wide-field and high-power viewing options on night one. The 6x30 finderscope offers a 7° field of view to help you easily locate your targets.

The Porta II mount completes the experience with thoughtful, field-tested engineering. Full-circle worm gear slow-motion controls let you fine-tune your alignment with precision, while the slip clutch friction system holds your position exactly where you leave it—without slipping or drifting. The handle positions rotate in 45° increments to accommodate different tube sizes and viewing angles, and the mount is rated to support optical tubes up to 5kg—making it a solid investment if you plan to upgrade later.

There are subtle features that make a real difference in practice. A built-in tool compartment under the mount’s rubber housing means you’ll never be without the tools needed to tweak tension or adjust handles in the field. The Vixen-standard dovetail plate allows you to swap optical tubes easily, giving you the freedom to expand your setup without replacing the whole system.

Portability and storage are equally seamless. The mount head detaches from the aluminum tripod with a single bolt, and the tripod adjusts between 705–1,200mm in height, with a footprint that expands from 370–606mm in radius. Whether you’re observing on a balcony, in a backyard, or driving to a dark sky site, the whole setup is compact, easy to pack, and quick to deploy.

Even better, it’s a complete system—not just a scope. Along with the eyepieces and finderscope, you’ll get a star diagonal, dew cap, accessory tray, fine-adjustment shafts, tube clamps, and a tripod shelf. Everything you need is included, with no hidden extras or surprise costs.

If you’ve been searching for a telescope that respects your curiosity—and rewards your investment of time—this is it. Thoughtfully designed, built to last, and crafted for real-world use, the Vixen Porta II A80Mf is the scope you’ll return to again and again. It doesn’t just show you the stars. It earns its place under them.
