SVBONY SV550 80mm Triplet APO Refractor Telescope — Premium Apochromatic Refractor for Astrophotography

The SVBONY SV550 80mm triplet APO is an apochromatic refractor telescope built for premium astrophotography and colour-true visual observing. "Apochromatic" means its three-element lens brings the colours of light to a common focus far more precisely than a basic scope, so bright stars and planets appear crisp and virtually free of the colour fringing that plagues cheaper refractors.

With 80mm of aperture and a fast 480mm focal length (f/6), it gives a wide, bright field that's ideal for deep-sky imaging, while a 2.5" dual-speed rack-and-pinion focuser (1:10 fine focus) delivers the precise, repeatable focus that sharp astrophotos demand.

Who it's for: Imagers and discerning visual observers who want a compact, high-quality APO for deep-sky photography and pin-sharp wide-field views. Learn the fundamentals in our beginner's guide to astrophotography.

• Triplet APO optics: one S-FPL51 ED element plus two correcting elements for tight colour control.
• Fast f/6 field: 480mm focal length frames large deep-sky targets brightly.
• 2.5" dual-speed focuser: rack-and-pinion with 1:10 fine focus for precise, repeatable focusing.
• Fully multi-coated: high transmission and strong contrast with minimal fringing.
• Imaging-ready build: internal baffles, blackened surfaces and a dovetail for accessories.

What you'll see: Visually, the SV550 80 APO shows the Moon with sharp, high-contrast detail and no false colour, Saturn's rings and Jupiter's belts cleanly, and rich star fields with pinpoint stars to the edge. For imaging it excels on wide deep-sky targets — nebulae, galaxies and large clusters — especially when paired with a matched flattener or reducer.

What does "apochromatic" mean?
An APO lens focuses the different colours of light to the same point far more precisely than a standard scope, producing sharp, colour-accurate views with negligible fringing.

Is it good for astrophotography?
Yes — its fast f/6 triplet optics and dual-speed focuser make it an excellent compact deep-sky imaging scope, especially with a matched flattener or reducer.

Do I need a flattener or reducer?
For visual use, no. For imaging across larger sensors, a matched field flattener (or 0.8x reducer) gives the sharpest corners.

Does it include a mount?
This is an optical tube; pair it with a tracking equatorial mount for astrophotography or a sturdy alt-azimuth mount for visual use.
