To ensure that everyone has a safe and enjoyable experience when observing at a NHAC site, we ask that everyone please follow these guidelines:

• There should be no smoking in the vicinity of the telescopes. Smoke can harm telescope optics, and can be quite irritating to some people. If you must smoke, please smoke only downwind from the observing area, and take your cigarette butts with you when you leave.
• Likewise, if you use aerosol sprays such as insect repellent, please use them downwind from the observing area. Wind-borne spray particles can also harm optical equipment.
• Do not use white lights after sunset. It takes time for a person’s eyes to become fully dark adapted, and white light will ruin this dark adaptation. You cannot see fainter objects unless your eyes are fully dark adapted. Only dim red lights are allowed on the observing field. Once your eyes have adapted, you will be able to find your way around in the dark.
• The same rule applies to car headlights. Try to arrive before sunset, if possible. If you do arrive after sunset, please turn off your headlights before approaching the observing area. The same rule applies when you leave, since others may still be observing. Turn on your headlights only after you have left the main observing area.
• If you have any trash, take it with you when you leave. No littering!
• NO FLASH PHOTOGRAPHY! It is prohibited after sunset, since the flash may ruin the night vision for all persons in the area.
• Please supervise your children! Children are welcome at the observing site, but younger ones may get lost or injured if allowed to wander around in the dark. They could also accidentally bump into someone’s expensive equipment.
• Please respect the equipment of other observers. Do not touch another person’s equipment without permission, and especially avoid touching the optical surfaces of eyepieces. If you have children present, please caution them about this rule also.
• No alcoholic beverages, fireworks, or firearms are permitted in the observing site.
• Proper conduct is essential. Rowdy or disruptive behavior is not permitted. Members are accountable for the actions of their guests.
• If you want to listen to music, please use your own personal headphones.

THANK YOU FOR YOUR HELP! ENJOY YOUR VISIT!
