TIPS
FOR BEGINNERS
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 min-
utes to relieve eyestrain.
Try not to use a standard flashlight. A lot of
observers use red LED flashlights or tape red
cellophane o
v
er their flashlights to use f
or
setup and map reading so the
y don’t ha
v
e to
contin
ually readjust their e
y
es to the dar
kness
.
Be careful not to shine br
ight lights if there are
other obser
v
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
f
or 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 25mm e
yepiece to view terrestrial
objects and wider areas of space
, such as
open star clusters
.
Use y
our 9mm eyepiece
when y
ou wish to vie
w something up close
,
such as cr
aters on the Moon or the r
ings of
Satur
n.
Know your observing site. If you’re going to try
out an unfamiliar site, check it out in the daylight
for possible obstructions and pitfalls.
