This exercise simulates the operation of a telescope and photoelectric
photometer.  Begin by selecting "Log In" on the main menu, and fill in
the requested information.  After completing the log in, select "Start"
on the main menu.

The control panel that appears has three major parts.  The telescope
controls and readouts appear on the left, the photometer controls and
readouts appear on the right, and the star field is displayed in the
center.

Press the "Dome" button to open the dome and the star field will appear.
Pause for a moment and notice that the stars slowly drift Westward in
the field as the Earth turns.  Press the "Tracking" button to stop this
motion.

The controls that move the telescope are below the "Tracking" button.
The "Slew Rate" button selects the speed of the motion.  Try moving the
telescope around at various speeds with the N-S-E-W buttons.  (To move
the telescope, press and hold a directional button.  Releasing the
button stops the motion.)  On a long slew, the motion may momentarily
stop and the words "Slew Reset" appear in the upper left of the screen.
If you continue to hold the button, the motion will resume after a few
seconds.  If you release the button, you may press it again when the
message disappears.

You are now ready to begin taking photometric data.  The operation of
the photometer is described on the "Taking Data" Help screen.
