HELPFUL HINTS
9.
1. Your telescope is a very sensitive instrument. For best results and fewer vibrations set your
telescope up on a level location on the ground rather than your concrete d
riveway or your
wooden deck. This will provide a more stable foundation for viewing, especially if you’ve
drawn a crowd with your new telescope.
2. If possible view from a location that has relatively few lights. This will allow you to see much
f
ainter objects. You’d be surprised how much more you’ll see from your local lake or park
when compared to a backyard in the city.
3. Using your telescope out a window is NEVER recommended.
4. View objects that are high in the sky if possible. W
aiting until the object rises well above the
horizon will provide a brighter and crisper image. Objects on the horizon are viewed through
several layers of earth’s atmosphere. Ever wonder why the moon appears orange as it sets on
the horizon? I
t’s because you are looking through a considerable more amount of atmosphere
than you would directly overhead. (Note: If objects high in the sky are distorted or wavy, you
are probably viewing on a very humid night.) During nights of unstable atmosphere, viewing
through a telescope can be frustrating if not impossible. Astronomers refer to crisp, clear
nights as nights of “good seeing.”
