Abstract

PURPOSE: To make an astronomical telescope easy to use by so constructing a finder that is can slew around a main mirror while its optical axis is being maintained parallel to the optical axis of the main mirror.
CONSTITUTION: The convex part of the oscillating part 11 of the fixing part 10 of a finder 1 is fitted in the recess having a U-shaped section at the end of the fixing part 10, and a tapered revolving shaft 13 is provided through both and is locked up by a set screw 15 by way of washers 14a, 14b. The finder 1 may be rotated about 180° while its optical axis is being maintained parallel to the optical axis of a main mirror, by adjusting the friction of an oscillating part 11 by tightening and loosening the screw 15. If the holding device 20 of the finder 1 is so built as to make cylindrical fitting to the outside circumference of a main mirror barrel 2 and is fixed by a clamp 21, the rotation of 360° is similarly possible.
