LX90 TIPS

Observing Considerations

• Try to pick an observing site away from street and house lights and car

headlights. While this is not always possible, the darker the site, the better.

• Give your eyes about ten minutes to adjust to the darkness before observing.

Give your eyes a rest from observing every ten or fifteen minutes to relieve

eyestrain.

• 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 obser

ers in the area.

Do not shine a flashlight into the

telescope while someone is obser

ving!

• Dress warmly. It gets chilly when you’re sitting for prolonged periods.

• Practice setting up your equipment during the day or in a lighted area to

become familiar with it before going to a dark site.

•

Use y

our 26mm eyepiece to view terrestrial objects and wider areas of space,

such as open star clusters

Use optional higher power eyepieces, such as a

9mm e

epiece (see

OPTIONAL A

CCESSORIES

, page 41 f

or more details), when

ou wish to vie

w something up close, such as craters on the Moon or the rings

of Satur

• Invite your friends and family to come and observe with you. But practice

locating 3 or 4 objects to show them beforehand; if you have long delays, they

will become bored and lose interest. Also, demonstrate how to focus the

telescope in a well-lit area before you go to to the observing site.
