| Star Projector Operation | Console Overview | Anatomy of Star Projector |

Switch special indicator projectors (such as cardinal points, ecliptic, etc.) on and off.
View or control accessories (such as reading light, indicator dials, desk illumination).

Try each operation listed below. Then confirm the machine's response, using a flashlight to view the star projector to identify the star projector components/motions as they are used. Instead of flashlights, you may use the Goto Spotlights controlled with the lighting panel; labelled SGS and NGS.

NOTE: For all star projector dimmer control knobs that fade projector lamps up and down, clockwise rotation (to the right) increases brightness, while counterclockwise rotation (to the left) decreases brightness. Setting the knob as far to the left as possible turns the projector off.

Middle row
right side
(EE on diagram) Equator/ Ecliptic Projects the ecliptic and equatorial coordinates
The "on" switch illuminates the ecliptic and equatorial coordinates together, the "off" switch cuts them off.

Middle row
right side
(M on diagram) Meridian Projects the meridian line
None

Middle row
right side
(Az on diagram) Azimuth Projects the azimuth angle for use in horizontal coordinates
None

Middle row
right side
(Z on diagram) Zenith Projects the zenith point of the dome
None

Middle row
3rd from right Polar Point Projects the north and south polar points in the sky.
The north polar point is represented by a red arrow, the south polar point by a green arrow.

Middle row
2nd from right Precession circle
and Galactic Pole Projects the precession circle and galactic pole simultaneously
None

Middle area, beneath Script Holder Recess (C on the diagram, with S to its left and N to its right) Cardinal Points Indicates the East, West, North and South directions in either red or green labels.
When changing latitude, the north & south, and east & west directions will reverse when either the north or south poles pass the zenith. If a polar point passes through the zenith, click the NORTH or SOUTH buttons to display the cardinal points accordingly, as either red or green abbreviations, corresponding to whether the north point is in the true north and the south point is in the true south (use red), or whether the north point is in the true south and the south point is in the true north (use green).

Bottom row
3rd from left Desk Lamp To see script or notes during a presentation
1. The dimmer control knob for the red lights along the left and right sides of the Script Holder Recess.

2. To avoid any detrimental effect to the show, keep the light level as dark as possible. Keep off when not in use.

Bottom row
3rd from right Pointer Adjusts brightness of two hand-held pointer arrows
1. The on/off switch is on the pointer itself.

2. Adjust the brightness by turning the panel dimmer control knob.

3. Do not turn the dimmer control knob for the pointers off when shutting down.
