With the SLD130, Tecnosky offers a large triplet refractor with FPL-51, lanthanum and low-dispersion glass, which can be used both visually and photographically in all areas of astronomy. The "medium" aperture ratio of f/7 allows for planetary observations as well as deep sky photography - with the matching RED130 V2 flattener from Tecnosky, you get a flat field for full-frame sensors.
The large 3.7" focuser is equipped with a 1:10 fine focus mechanism and is stable enough to hold even heavy DSLR cameras.
