SVBONY SV550 Telescope 80mm Triplet APO OTA Refractor for Astronomy

OPEN BOX / NEW!

The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, is a great travel telescope for deep-sky observation and astrophotography.

Apochromatic triplet, it uses a series of three lenses. It provides better correction of aberration and significantly reduces dispersion. It reduces chromatic aberration, and it corrects for two wavelengths to reduce spherical aberration. The apochromatic triplet objective provides high-quality, sharp and high-contrast images.

The focal length is 480mm, suitable for deep sky observation and photography, for galaxies, nebulae, star clusters and other deep sky objects.

The gear ratio of the dual speed 2.5-inch toothed focuser is 1:10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, for fast focusing and fine focusing.

Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast.
