Description: . . 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. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, for fast focusing and fine focusing. SV550 refractor is compatible with 2-inch and M63*1 accessories. The front is a 2-inch adapter for connecting a camera or 2-inch accessories; Rotating off the adapter, here threaded the M63*1 threads, for connecting the SV219 field flattener or other M63*1 accessories. Lock the focus, observe without distortion. The focusing thread locking device improves accuracy and longevity. Made from high-quality optical materials, ensuring clear, realistic observations.Unique material processing techniques make this product outstanding in quality and durability. The entire tube rings have 26 screw holes + a mounting screw handle. Such tube rings with so many screw holes can be compatible with more equipment installations, like Smart WIFI device, guide scope, astronomy camera etc., meeting various needs of installations. Professional pairing for a professional observation experience.Connects to eyepieces or works with finderscopes and zenith mirrors for high-quality visual observations. Professional pairing for professional astrophotography resultsWorks with finderscopes, electronic eyepieces, and focal reducers to meet a variety of astrophotography needs. The length of the dovetail is as high as 300mm, which is longer than the length of most dovetails on the market. It can maintain the balance to the greatest extent, and it will be more convenient in the adjustment process. The two entire tube rings have 26 screw holes, compatible with more equipment installations, meeting various needs of installations.
