• Try not to use a standard flashlight. Experienced observers use red LED
flashlights, the red utility light on the AutoStar handbox or tape red cellophane
over their flashlights to use for setup and map reading so they don’t have to
continually readjust their eyes to the darkness. Be careful not to shine bright
lights if there are other observers in the area. Do not shine a flashlight into the
telescope while someone is obser
ving!

Dress w
armly. It gets chilly when you’re sitting for prolonged periods.

Invite your friends and family to come and observe with you. But practice
locating 3 or 4 objects to sho
w them beforehand;if you have long delays, they
will become bored and lose interest.
Also, demonstrate how to focus the
telescope in a w
ell-lit area before you go to to the observing site.
