The SV550 APO Triplet refractor is a compact refractor with 122mm aperture, f/7 focal ratio and 854mm focal length, a great travel telescope for astrophotography and observation. The OTA weighs only 6.44kg/ 14.18lb, easy to carry out when fitting into the carrying case. SV550 122 is an absolutely upgraded version of the SV550 80mm. The refractor gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation, for galaxies, nebulae, star clusters and even some fainter deep sky objects, due to the higher limiting magnitude. The SV550 122mm adopts a FPL-51 triplet apochromatic lens structure which contains one piece of ED glass. The triplet lens provides better correction of aberration and significantly reduces chromatic aberration and enhance the clarity and sharpness. The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus.
