Remember, even bright red lights could ruin someone's astrophotography efforts. If you plan to stay all night, park away from the exit. If you are leaving early, park near the exit. If you do not have a telescope, park away from the observers and walk over. If you absolutely have to leave at any other time, please yell a warning five minutes before you leave so that astrophotographer have time to save their photos, and others can shield their eyes.
Smoke is inhibitive or even corrosive to certain optical systems.
Do not bring alcoholic beverages - these have no positive effect physiologically or mentally at events such as these where your senses must be at their best. Otherwise, feel free to mingle, ask questions. We do not wish to appear as though our star parties are regulated by Nazis, but these guidelines help all to enjoy the opportunity.
