We present the results of 3489 astrometric observations for 361 visual double stars performed in 2003–2007 with the 26-inch refractor of the Pulkovo Observatory. The angular separations between the components (
ρ
) and the position angles (
θ
) are given. The errors in these quantities are, on average, 0″.009 for
ρ
and 0°.40/
ρ
for
θ
, where
ρ
is the separation in arcseconds.
