The NA130SSWT refractor is a neo-achromatic system. The telescope is basically a normal achromat, but with a two lens element corrector inserted into the light path. This flattens the field of view and ensures higher light intensity. Chromatic aberration correction is also significantly improved. It has such a large aperture that it can compete with a reflecting telescope in terms of light intensity, as with no central obstruction it beats all reflectors on contrast. Lens diameter 130mm
f = 800 mm, f6.1
7X50 finder scope
2" focuser
