This tool is to control the connection to the planetarium.
It is used to display an astrometry resolved image with the right click menu, or to set the targets coordinates in the sequence preparation.
Click the New target button, click or search an object in the planetarium, then click OK.
This make a plate solved slew to the object position and set the object name in the Capture tool.
You must have a camera and mount connected before you can use this function.
The same box is used in the sequence editor to set the target coordinates.
Note that the target coordinates are apparent and could differ from the planetarium if the planetarium displays the position in equinox J2000 coordinates.
