Can I have any light on the field?

This is a dark site. Since it is very easy to lose your dark adaptation, the use of glow sticks or any source of white light is prohibited. Only low-powered, red-filtered flashlights are permitted in the observing areas.

The prohibition also covers white lights inside tents which might be visible on the field. Lights in cars (dome lights, door lights, etc.) which may come on remotely or automatically need to be covered or adequately filtered.

Laser pointers may not be used, as they interfere with observers doing astrophotography. There is one exception to this rule: we may conduct a “star tour” just after dark as part of the formal program using a laser pointer.
