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
driveway 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 fainter 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. Waiting 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? It’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."
