Abstract
Abstract The observations of faint stars are very effective with a CCD eyepiece micrometer. Such a micrometer was designed for the Axial Meridian Circle (AMC) of the Mykolayiv Astronomical Observatory. It includes the CCD matrix 256 × 288 with pixel size 32 × 24 μm. The matrix is mounted into a vacuum camera and cooled down to -40° C with thermoelectric Peltier elements. PC/AT-486 is used in the capacity of control computer. The trials investigation of the pilot CCD micrometer showed positional accuracy of 0.1 arcsec for objects up to 11 magnitude.
