10
POSSIBLE OBJECTS
FOR OBSERVATION:
Terrestrial objects
Take note of the examples below, including
Mount Rushmore and the golf course.
Start with the 20 mm eyepiece and focus
until the image is clear. After mastering
the 20 mm eyepiece, switch to the 12.5
mm eyepiece and practice scanning and
focusing until the image is clear. Choose
several terrestrial objects to practice
focusing on, but never point your telescope
at or near the sun, or you risk blindness.
The Moon
Diameter:
3,476 km
Distance:
Approximately 384,401 km
The Moon is the Earth’s only natural satellite,
and it is the second brightest object in the
sky (after the Sun). Although it is our closest
neighbor, a lot of people have never really
taken a good long like at the Moon. With
your telescope, you should be able to see
several interesting lunar features. These
include lunar maria, which appear as vast
plains, and some of the larger craters. The
best views will be found along the terminator,
which is the edge where the visible and
cloaked portions of the Moon meet.
