This tool display the current telescope RA/DEC and Alt/Az position, the side of pier if reported by the driver, the time to or from the meridian.
You can Park or Unpark the mount using the corresponding button.
The Track button start the mount tracking.
Click the Goto button to move the telescope to a new position.
After the coordinates are entered, the target Azimuth and Elevation is show, so you can check if it is safe to slew the telescope there.
If you not want a precise centering of the object you can uncheck Use astrometry to refine the position. In this case a simple Goto is done, without plate solving.
There is an indication the Goto is in progress and you can stop it using the Stop button.
