The lists of observations in 2011-13 are compiled. They include 68 asteroids with magnitude up to 19 for RTT-150 telescope and 62 asteroids with magnitude up to 17 for Mobitel telescope. 394 astrometric positions of 14 asteroids are received from observations at the Mobitel telescope in 2011, with standard deviation for one position of (0.07-0.38)" in right ascension and (0.06-0.60)" in declination for (10-17) magnitudes in the UCAC3 reference catalog system. 777 astrometric positions of 19 asteroids were received from observations at the RTT-150 telescope in 2011, with a standard deviation of about 0.10" in right ascension and 0.08" in declination for (15-19) magnitudes in the UCAC3 reference catalog system. The software for editing FITS-file with observations were created. The estimates of systematic errors for the differential chromatic refraction for observations of stars of different spectral classes were carried out.
