  1. Florescent worklights
    Located on the peripheral walls, behind the gallery. These lights are not controlled by Hercules (and will not be used during shows). Turn them on and off with wall switches near either entrance to the room and near the console area.

    The other lighting systems are controlled through Hercules automation (using the lamp commands listed below) or manually with the Cygnus Light Panel.

     

  2. Layout of the Cygnus Light Panel.
    For a key to the abbreviations used, see the Configuration List.

    • The nine theater lights (TL#) are controlled primarily through automation; therefore they are placed out of the way on the right side of the panel. The theater lights are numbered from the north end of the projection booth (TL1) to the south (TL9).
    • The top row (left side) of the panel includes the lights used during entry (ENTR, FL, SGS, NGS). Beneath them are the spotlights (CS, SS). The quartz worklights (never used during a show) are on the lowest row (NSQ, EWQ).
    • Four knobs are spares, not used with existing systems.
    • Lighting circuits connected to the Cygnus panel are numbered as follows:

  3. Quartz worklights
    Quartz worklights are installed on the cove pointing upward to provide indirect room lighting for work purposes. The North-South Quartzlights (NSQ) are on one circuit, and the East-Southwest Quartzlights (EWQ) are on a second. Although both circuits are controlled through the Cygnus light panel, quartzlights are never used during a show.

     

  4. Theatrical lights Theatrical lights can be used in a variety of combinations and automated sequences for special effects (e.g., shimmering gaseous nebulas), sky simulations (e.g., reddish atmosphere of Mars), etc.

     

  5. Star Projector Spotlights Decorative lighting for the star projector originates from cove shelf spotlights to illuminate the south side of the projector (SGS) and north side (NGS).

     

  6. Entry/Exit lights Entryway lighting (ENTR), either red or blacklights, illuminate the audience entryways.

     

  7. Footlights Red footlights (FL) allow safe entrance and egress from the planetarium during low light conditions.
