The Vixen Porta II ED80Sf is for you if…

• You’ve outgrown your beginner telescope and want a serious upgrade with color-accurate optics — but don’t want to commit to a heavy equatorial setup.
• You regularly travel to dark-sky sites and need a compact, no-fuss telescope that fits in your car or carry-on without compromising image quality.
• You’re frustrated by chromatic fringing on planets or the Moon in cheaper scopes, and you're ready for high-end optics that deliver pinpoint stars and natural color.
• You prefer hands-on observing with the tactile feel of slow-motion controls — and don’t want to rely on electronics, apps, or auto-alignment systems.
• You want to dip into basic astrophotography — especially planetary or lunar imaging — using your DSLR, and need a scope that’s already built for it.
• You’re looking for an all-in-one, thoughtfully curated package that doesn’t require guesswork, adapter hunting, or post-purchase accessories.

You’ve spent hours comparing optics, scanning forums, and watching review videos. You’re not just looking for a telescope — you’re after a serious instrument that travels as well as you do, performs like it should, and doesn’t leave you second-guessing your gear. The Vixen Porta II ED80Sf was built for that exact kind of astronomer.

This isn’t your average 80mm scope. With its premium ED apochromatic lens, it gives you the kind of clarity and color fidelity that entry-level refractors can’t touch. Planets show crisp surface detail. Star clusters pop. And most importantly — there’s no distracting purple fringe around bright targets.

You get two eyepieces out of the box, giving you 33x wide views with the 20mm and 103x with the 6mm — perfect for lunar craters or tight planetary transits. Paired with the 9x50 finder’s 4.8° field of view, star-hopping becomes fast, intuitive, and satisfying. And with a resolving power of 1.45 arc seconds and 131x the light-gathering power of the unaided eye, the scope reveals faint deep-sky objects and sharp planetary detail with ease.

The Porta II mount is mechanical simplicity done right. Forget the buzz of motors or confusing GoTo menus. You get fine, fluid control in every direction with slow-motion handles that adjust in 45° increments — ideal for finding a comfortable grip with any scope or setup. And with a 5kg load capacity, the mount handles this OTA with stability to spare, even when you add cameras or heavier accessories.

Even the tripod and mount separate with a single bolt, making setup and teardown fast — no awkward folding or tool juggling required. The tripod extends from 70 to 120 cm in height with a wide stance of up to 606 mm, giving you comfort and stability on almost any surface. And when you do need to tweak handle positions or friction, your tools are tucked into a hidden compartment right under the mount’s rubber covering — a small but brilliant detail for observers who like to fine-tune.

The included flip mirror is a game changer. Not only does it simplify visual observing, it also has a built-in T2 thread so you can attach a DSLR in seconds — no hunting for adapters or struggling to refocus. Combined with the Crayford-style focuser, it makes your first steps into astrophotography smoother and more precise.

And if you're thinking long-term, the dovetail-plate system gives you the flexibility to swap optical tubes easily — no commitment issues here. Whether you’re upgrading your OTA or exploring other configurations, your mount grows with you.

What makes this setup special is its balance: it’s light enough for road trips and spontaneous skywatching, yet refined enough for serious observation and imaging. And the best part? It’s a complete, well-curated package — mount, optics, finderscope, eyepieces, tripod, flip mirror, dovetail bar, and a padded carry case. No guesswork. No add-ons required. Just everything you need to elevate your observing game — right out of the box.
