Astronomy doesn’t deserve

its reputation as a tough,

expensive hobby to get

into. You just need

to begin with the right

advice.

way around the sky. They also give you a

view that’s right side up and straight in

front of you, making it easy to see where you’re pointing. Binoculars are fairly inex-pensive, widely available, and easy to carry

and store. They’re also versatile; you canswitch from terrestrial to celestial viewingin an instant. And their performance is

surprisingly respectable. Ordinary 7- to 10-power binoculars improve on the unaided

eye about as much as a good amateur tele-scope improves on binoculars — and at a

far lower cost. For astronomy, the largerthe front lenses are, the better. High opticalquality is important too. But any binocu-

lars already knocking around the back of your closet are enough to launch your

amateur-astronomy career.

Use Maps and GuidebooksOnce you’ve learned your way around thenight sky, binoculars can keep you busy

for years. With good maps and referencebooks, you can identify dozens of the

Moon’s craters, plains, and mountains.Binoculars will show you the ever-chang-

ing positions of Jupiter’s moons and thecrescent phases of Venus. They’ll alsoreveal most of the 109 “M objects,” the star

clusters, galaxies, and nebulae cataloged by 18th-century astronomer Charles Messier.

Binoculars will let you split scores of col-orful double stars and allow you to follow

the fadings and brightenings of numerousvariable stars. All this and more is possible

— but only if you know where to look andwhat to look for. Moreover, the skills you’lldevelop using maps and guidebooks with

binoculars are exactly the skills you’ll needto put a telescope to good use.

Seek Out Other AmateursThere’s nothing like sharing an interest withothers. There are hundreds of astronomy clubs worldwide; Sky & Telescope ’s Web site

includes a directory of them. Call a clubnear you to find out when it holds meetings

or all-night observing sessions called “starparties.” These events offer a wonderful

opportunity to try out different telescopes,learn new skills, and make friends.

When It’s Time for a Telescope,Plunge in Deep

Eventually you’ll be ready for your first telescope. This is no time to skimp on quality.The telescope you want has two essentials.

One is high-quality, “diffraction-limited”optics. The other is a solid, steady, smooth

ly working mount. You may also want largaperture (size), but don’t lose sight of portability and convenience. Remember, the

best telescope for you is the one you’ll actually use.

Many telescopes have built-in comput-ers and motors that will point them to an

of thousands of celestial objects at the

push of a few buttons. These are a lot of fun to use and can help you locate sights

you might otherwise overlook. But it’s stilhelpful to know your way around the sky

— especially if your batteries run out!It’s true that telescopes can cost many

thousands of dollars, but it’s also true thasome good ones can be had for only a fewhundred dollars. Can’t afford the scope

you want? Save up until you can. Another year of using binoculars while building a

savings account will be time you’ll never

regret.

Relax and Have FunDon’t get upset if you can’t find a particu-

lar object or because the view in your tele-scope is less than perfect. Learn to take

pleasure in whatever your eyes, binocularsor telescope can show you. The more you

look, the more you’ll see. Set your ownpace, and revel in the beauty and mystery

of our amazing universe!

DID YOU KNOW THAT YOU can see a galaxy

21 ⁄ 2 million light-years away with your

unaided eye? Or that you can see craterson the Moon with ordinary binoculars?These and countless other wonders await

your gaze every clear night. The first stepis simply to look up and ask, “What’sthat?”And when you do, you’ll take the

first step toward a lifetime of cosmicexploration and enjoyment. What’s the

best way to get started on this excitingadventure?

Read It and ReapThe joy of astronomy comes from finding

your way around the starry sky andunderstanding what you see. A great place

to start is your local library or bookstore.Browse the astronomy shelf for beginner’s

guides that will teach you about theMoon, planets, and constellations. Checkthe magazine rack for Sky & Telescope , the

hobby’s essential monthly magazine. Itoffers practical tips for observers as well as

articles on many fascinating astronomicaltopics.

Another great resource is the WorldWide Web. Start at Sky & Telescope ’s site,SkyandTelescope.com, or you can use any

search utility to look up topics such as“amateur astronomy” or “stargazing.”

Let the Stars Get in Your EyesGo out on any clear, dark night and famil-iarize yourself with the star patterns over-

head, using the constellation maps on thefollowing pages.

If you live in a brightly lit city or town,

find a place where there’s less light pollu-tion (or at least a spot free from the glare

of nearby lights) so you can see morestars. The ability to look up and say,

“There’s Alpha Centauri!” or “That’sSaturn!”will provide pleasure — and asense of your place in the cosmos — for

the rest of your life.

Start with BinocularsBinoculars are an ideal “first telescope”

for several reasons. They show you a widefield of view, making it easy to find your

Your First Stepsin Astronomy

S o u t h e r n H e m i s p h e r e V e r s i o n



Looking DeeperTake the maps out often, and try to learn a

new constellation each night. You are estab-lishing the landmarks you’ll need for find-

ing your way when you start using binocu-lars or a telescope.

Once you know at least some constella-tions fairly well, you can start exploring thesky a lot more deeply with optical aid. For

this you’ll need larger star charts that showmore close-up detail.

The maps here show stars as faint asmagnitude 4.5. This is about as faint as you

can see with the naked eye through subur-ban light pollution. Also plotted are some

interesting objects for binoculars or smalltelescopes: star clusters, nebulae, and galax-ies. When hunting for these faint sights

you’ll have an easier time if you use largercharts that show stars to at least as faint as

magnitude 6. (Higher magnitude numbersmean fainter stars.)

People who get serious about using a tel-escope will want even more detailed sky charts — ones that show stars as faint as

magnitude 8 or so. Sky Atlas 2000.0 by WilTirion and Roger W. Sinnott is the set most

widely used. The latest edition shows 81,000stars to magnitude 8.5 and 2,700 galaxies,

star clusters, and nebulae.Clear skies!

Greek Letters on Star MapsThe brightest stars in each constellation are

named with lowercase Greek letters. A con-stellation’s most brilliant star is often called

Alpha, the first letter in the Greek alphabet.The letters are used with the Latin genitiveform of the constellation name, so the

Alpha star of Centaurus is called “AlphaCentauri.”

Here is the lowercase Greek alphabet as

used by astronomers:

α Alphaβ Betaγ Gammaδ Deltaε Epsilonζ Zetaη Etaθ Theta

CAN YOU SPOT THE SOUTHERN CROSS? Orion?

The Large Magellanic Cloud? Your explo-ration of the universe begins with learning

the stars in your evening sky. But differentconstellations are visible at different times of

year and hours of the night, depending on

your latitude and which way the night sideof our planet is facing.

The accompanying charts will help youget oriented. They’re designed for skywatch-

ers in midsouthern latitudes such as Aus-

tralia, southern Africa, and parts of SouthAmerica. Each represents the entire sky atthe dates and times printed on it. Find achart appropriate for your date, and go out

within an hour or so of the time listed.

How the Charts Work The round edge of each chart represents your

horizon, with compass directions labeled.Turn the map around so the edge markedwith the direction you’re facing (north, east,

or whatever) is right-side up. The stars abovethis horizon on the map will now match the

stars you’re facing. Ignore the rest of the mapfor now.

The map’s center is overhead (the zen-tih). So a star that’s plotted halfway fromthe edge to the center can be found about

halfway up the sky. That is, it will behalfway from horizontal to straight up.

Dot sizes indicate star brightnesses —the larger the dot, the brighter the star.

Example: Let’s try the May/June chart. Turnit so the horizon labeled “Facing SW”(southwest) is right-side up. About a third

of the way from there to the center is thebright star Canopus. Go outside around

one of the dates and times listed, facesouthwest, and look a third of the way from

horizontal to straight up. There’s Canopus!To the left of Canopus is the fuzzy Large

Magellanic Cloud (LMC), one of our Milky

Way’s satellite galaxies. Still farther left, al-most due south, is the Small Magellanic

Cloud (SMC). Turn the chart so the “FacingSouth” horizon edge is right-side up. When

you hold the chart correctly, the SMC is di-rectly in front of you and not very high up,

Here’s how to use our bimonthly

star charts to identify your

evening stars and constellations.

Finding Your Way

Among the Starsand the LMC is to the right and a little high-

er — just the way they look in the southernand southwestern sky. Nearly overhead, as

you crane your neck up, are the bright stars

Alpha (α) and Beta (β) Centauri, with thelittle constellation Crux — the Southern

Cross — to their right.

Tips for SuccessFind a dark viewing site and bring a dimflashlight to read the map by. It’s best to use

red light, which helps preserve your nightvision.

When you start out, look only for thebrightest stars on the map, those depicted

with the biggest dots. Mentally blank out thefainter ones if you are in a city or suburb (or

in bright moonlight); they will be invisible ornearly so through the “light pollution.” Butwherever you are, remember that there is a

much bigger difference between bright andfaint stars in the sky than is suggested on the

chart.Remember that the chart is a very

reduced representation of the real sky. To

see how reduced, hold your hand at arm’slength with your fingers fully spread as

wide as you can. One of these “hand spans”from thumbtip to little fingertip is about

the separation between the LMC and SMC.Compare this with the gap between themon the charts. You can work your way

around by remembering this rule: Onehand span in the sky is slightly less than an

inch on the chart. Pretty tiny!The maps are drawn for an observer at 35°

south latitude (for example, Sydney, CapeTown, Santiago). If you’re far south of there,

stars in the southern part of the sky will ap-pear higher than the map shows, and stars inthe north will be lower. If you’re far north of

35° latitude, the reverse will be true.

The Moon and planets are not plottedbecause they’re always changing position.Find the line arcing across each chart

labeled “ECLIPTIC.” This is the line nearwhich the Sun, Moon, and planets alwaystravel. It’s called the ecliptic because it’s

where eclipses can occur.If you see a bright “star” near the ecliptic

that’s not on the map, you’ve located aplanet. To figure out which one it is, con-

sult the latest issue of Sky & Telescope orvisit SkyandTelescope.com and use ourInteractive Sky Chart.

When to Use This ChartEarly Jan. 11 p.m.

Late Jan. 10 p.m.Early Feb. 9 p.m.

Late Feb. 8 p.m.

These are standard times. The chart is alsouseful in late October at dawn, lateNovember at 3 a.m., and late

December at 1 a.m.

How to Use This ChartGo out within an hour or so of the time listed at left.

Turn the chart around so the edge marked with thedirection you’re facing is right-reading. The starsabove this horizon on the map now match the stars

in front of you. The map’s center is overhead (thezenith). So a star plotted halfway from the

edge to the center can be found inthe sky about halfway

from horizontal tostraight up.

waxing (growing) crescent, we see the parts

on the right edge of the map. At first-quarter

phase we see the entire right half, and so on.To use this lunar map, turn the chart

until it matches your view. Note: Some tele-

scopes give a mirror image, which will notmatch this map no matter how you turn it.

Refractors and Cassegrain reflectors give

mirror images when used with a star diago-

nal; so does any other instrument contain-ing an odd number of mirrors. If you findthis to be a problem, take out the star diag-

onal and view “straight through.” A correctimage is much easier to compare with any map.

Once the map is oriented, it will besimple to identify the major craters,

mountains, and other features.In time, the geography of

this alien world will be-come as familiar to

you as that of

our own.

The Moon is by far the most rewarding ce-

lestial object for a small telescope. Even a

very small instrument will reveal its bleak,blasted landscape of mountain ranges,plains, hills, valleys, and craters. Even

binoculars show many features, and thereare enough interesting sites on the Moon tokeep a telescopic explorer busy forever.

You’ll notice right away that exceptwhen the Moon is full, it is divid-

ed by the terminator, the lineseparating lunar day and

night. Here is wheredetail shows best.
