The Nanshan One-Meter Wide-field Telescope (NOWT) was installed in March 2012. A distinctive feature of NOWT is its Alt-Azimuth mount configuration operating at prime focus with a field corrector. The effective field-of-view (FOV) is 1.37 degrees×1.37 degrees. The imaging system comprises a CCD camera mounted above a field derotator and a filter wheel. The filter wheel, featuring five positions, accommodates either the standard Johnson-Cousins (UBVRI) filters, the Sloan Digital Sky Survey (u’g’r’i’z’) filters, or the Strömgren (uvby) filter set.
