| To safeguard optics and other equipment, all Lick telescopes are subject to closure due to wind, humidity, snow, and ash-fall. 3-meter limits are the responsibility of the telescope operator. At all other telescopes, the observer is responsible for the safety of the equipment. See Weather and Pointing Limits. |
