SVBONY 80MM F/6 APO TRIPLET (SV550)

The SVBONY SV550 80mm is an apochromatic triplet refractor combining an S-FPL51 extra-low dispersion element with two correcting lenses to deliver sharp, high-contrast views with minimal color fringing. Its 80mm aperture and 480mm f/6 focal length balance wide-field deep-sky imaging with pleasing visual observation, making it a highly portable instrument for astrophotography and visual use alike.

Features

• Triplet APO design: 3-element objective with one S-FPL51 ED element plus two correcting lenses for apochromatic correction.
• FPL51 ED glass: extra-low dispersion glass that minimizes chromatic aberration.
