- Аннотация: We have determined the realistic seeing of the 1.5-m AZT-22 telescope of the Mt. Maidanak Observatory (Astronomical Institute, Uzbek Academy of Sciences) using more than 20 000 CCD frames with stellar images in the UBV RI bands acquired in 1996-2005: epsilon = 1.065aEuro(3) in the V band. The characteristic seeing reduced to unit air mass, epsilon (med) (V) (M(z) = 1), is 0.945aEuro(3). We derived color equations for the CCD detectors used with the telescope. Atmospheric-extinction coefficients in different photometric bands were also determined. The mean V -band atmospheric extinction is 0.20 (m) +/- 0.04 (m) . The time needed for the conditions to settle, in the free atmosphere as well as inside the telescope dome, is 2-2.5 hours after the end of astronomical twilight. For nights with epsilon (med) (V) > 0.9aEuro(3), we find a persistent difference between the seeing found at this telescope and measured simultaneously with a differential image motion monitor, amounting to similar to 0.1 (m) .
