The red square in the center of the finder display shows the size of the
instrument field.  Move the telescope so that some stars are in the red
square and press the "Monitor" button.  The instrument field will appear
with a red circle at its center indicating the position and size of the
photometer aperture.  You may change back and forth between the finder
and instrument fields whenever you like by pressing the "Monitor" button.
However, photometer measurements can only be made when the instrument
field is displayed.

You should begin your observations by taking readings of the sky.  Move
the telescope to a point where the field in the red circle is free of
stars.  Set the integration time to 10 seconds and the number of
integrations to 5.  Press the "Reading" button and wait for the reading.
Change the filter and repeat until you have measured the sky in all
three colors.

To measure each star, center it as accurately as possible in the red
circle.  Set the number of integrations and seconds so as to obtain
signal-to-noise ratios of at least 100, if possible.  Be sure to record
your results, and be sure to measure each star in all three colors.

To Quit: When you have completed your observing run, turn off tracking,
close the dome, and select "Quit" from the main menu.
