Apparatus for automatically introducing celestial object, terminal device and control system for astronomical telescope

A terminal device connectable to an automatic introduction apparatus for automatically introducing a target celestial object by controlling a rotation of an astronomical telescope around at least two axes, said terminal device comprising:

• an input operation section for executing a command operation on said automatic introduction apparatus;
• and
• an image display section for indicating a star map image for a predetermined area on a celestial sphere in accordance with a display scale factor,
• said input operation section having:
• a rotation command means for executing a command operation on a rotational driving of said astronomical telescope in a telescope control mode;
• and
• a scale factor input means for executing an input specification of said display scale factor for said star map image displayed in said image display section, wherein
• in said telescope control mode, a star map image corresponding to a position on a celestial sphere toward which said astronomical telescope is headed is displayed in said image display section, while a speed of rotation of said astronomical telescope controlled by said rotation command means is changed in accordance with a decreasing function of said display scale factor specified by said scale factor input means.
