FIELD: instrumentation engineering, measurement of angles of slope relative to horizon or vertical. SUBSTANCE: optical measuring instrument includes glass ampule 1 in the form of clear sealed cylinder, float 3 with circular plate 4 with angle measuring scale attached to it. Plate is made in the form of ring. Difference of outer and inner radii of ring is equal to 1/8-1/10 of outer diameter of entrance pupil of eye-piece of telescope. EFFECT: enhanced measurement precision. 3 dwg
