| Abstract: | A new moving slit star micrometer has been developed for the 18 cm Carlsberg Automatic Meridian Circle on La Palma. A zenith mean error of 0

8 is obtained. It has a high efficiency and is well suited for improving the FK5 system and extending it to much fainter stars. A new collimator alignment micrometer and the necessary calibrations are also described. |
