Fields of Geminga, PSR B0950+08, PSR J1908+0734 and PSR J0108-1431 have been observed within the program of optical investigation of nearby neutron stars carried out with the 6m telescope. Our multicolour BVRcIc photometry has yielded the following magnitudes of Geminga: V=25.3+/-0.4; Rc=25.4+/-0.3. The estimates of the 3σupper limits in the B and Ic bands are 25.4 and 24.9, respectively. This is in agreement with previous observations of Geminga. We have suggested candidate for optical counterpart of PSR B0950+08, with Rc=25.4+/-0.3. When compared to the HST data obtained in UV its flux shows that this old pulsar can be brighter in near-IR than in near-UV. We have obtained for the first time images of the fields of PSR J1908+0734 and PSR J0108-1431. Although no optical counterparts have been detected, the magnutude upper limits obtained suggest further observations of these pulsars.
