Major works in the field of astronomical optics and instrumentation. He developed a number of ways to reduce the optical aberrations of the mirror and lens telescopes and spectrographs. Created by a mechanical system that reduces the influence of gravity to form reflector mirror; system used in telescopes and large at present. Establish rules mount mirrors. Recommended use of ventilation in the large telescopes to reduce the effects of air turbulence. According to his ideas and with his active participation, several new large reflectors were built.
