1.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. 2.Apochromatic triplet 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. 3.The focal length is 480mm, suitable for deep sky observation and photography, for galaxies, nebulae, star clusters and other deep sky objects. 4. Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast.
