Before getting a telescope,
you must answer several very important
questions to learn if you're ready for one
or to assure you get the right kind.
First, how well do you know
the sky? In other words, how many constellations
can you identify without a star map? Do you
know where all the planets are? Can
you point to at least a dozen "deep-sky"
objects without help? Can you predict
which stars, constellations
and planets will be in the sky tomorrow
morning at dawn?, etc.)
Second, what are you
interested in viewing―the
planets, the moon, the stars, deep sky
objects, the neighbors? Different
telescopes work best for different tasks
and, while there are some "all-purpose"
scopes, it's always best to know what
interests you most. Do you live in a
light-polluted location, or are you willing
to drive to a "dark-sky" site to use the
scope? Are you interested in getting
into sketching or photography of
astronomical subjects in the future, or
carrying out some basic research projects
from your home?
Third, do you want a computerized or manual
telescope? Computerized telescopes are
all the rage, but unless you're willing to
learn how they operate and to set them up
properly (most people aren't!), I recommend
against them―especially
for beginners. Manual scopes
(such as Dobsonian designs) will give you
much more bang for the buck since the entire
cost goes for optics rather than
electronics. And they help you learn
(and enjoy) the sky because you've got to
aim the telescope yourself.
And finally, (and sometimes
most critical) how much do you want to
spend? Telescopes are not toys (except
those sold in toy and department stores!)
and one cannot usually find a high quality instrument for less than about $250.-$300. Anything
less is often just a toy and, after the
initial fascination wears off, will likely
prove to be a waste of money.
While it would be easy to
"sell" you on a telescope, the truth is
that, if you can't answer the above
questions satisfactorily (i.e., if you
don't know where to aim a telescope or how
the sky behaves), I can promise that it'll
wind up in the closet collecting dust in no
time. (It's like using a piano―it's
pretty useless unless you FIRST understand
music.)
If you feel you're not quite ready yet, I'd
recommend getting a couple of basic books,
star maps, and possibly 7x50 binoculars
along with a tripod
(which are an excellent transition from
naked eye astronomy to telescopic studies―there are
excellent books out on all that can be seen
with binoculars.) These also help
teach about optics, light gathering power, magnification, focus, fields of view, and
more―all of
which are needed for proper use of a
telescope.
Visit any bookstore,
or a telescope store such as
Oceanside Photo & Telescope, for a good selection of
basic materials. You can get to know
your local
amateur astronomy club,
and participate in their "star parties"
where you'll be able to explore a variety of
telescopes before buying one. Or, to
learn more, you can register for some of my
lectures or basic
astronomy courses or
enrichment tours.
Give these points some honest
thought before rushing out to buy a
telescope. When you feel you are
ready, please feel free to drop me a note
and I'll try to help you further.
