Experience of television observations with meridian axial circles.

A highly sensitive television viewing system with silicon intensifier tube was used for meridian micrometric observations and allowed positions of stars ranging from 3 to 13 magnitudes to be measured. Measurements were carried out by means of controlling the images of stars and micrometric threads on videomonitor screen. The accuracy of one observation appeared to be ±0.3 - 0.5″in right ascension and ±0.2″in declination. This indicates the small effect of television distortion. With a more sensitive TV-camera (1.5 - 2^m) this method can be applied to meridian observations of quasars and other faint objects directly in the fundamental catalogue system.
