A re-reduction of observations made with ZTF-135 in Pulkovo during 1948.7-1989.0 (all together about 87 000 observations) has been carried out with the aim of determing the amplitude of the principal terms of nutation in longitude and obliquity. The derived coefficients of nutation M=6.“8445±″0033 and N=9.”2028±0.″0025 are in good agreement with similar astrometric determinations.
