He made so exact a micrometrical map of the great crater of the moon (Copernicus) that the Royal Society of London had numerous photographic copies made of it, and had them distributed among those interested in astronomy.

By ingenious improvements in mounting and fitting, it was adapted to the finest micrometrical work, and thus offered unprecedented facilities both for the examination of double stars (in which Struve chiefly employed it), and for such subtle measurements as might serve to reveal or disprove the existence of a sensible stellar parallax.
