The features of the astrolabe are that:

(1) a span of 6 hour of R.A. of star positions can be tied in a group of observation of 2 hours, all-night observation can cover more than half of the sky, and

(2) the declination system can be set up with high precision without the need of a precise circle (Li 1987).
