When you become an advanced 

observer you can look for other 

types of objects such as asteroids, 

planetary nebula and globular clusters. 

And if you’re lucky, every so often a bright 

comet appears in the sky, presenting an 

unforgettable sight.
The more you learn about objects in the 

sky, the more you will learn to appreciate 

the sights you see in your telescope. Start 

a notebook and write down the observations 

you make each night. Note the time and the 

date.
Use a compass to make a circle, or trace 

around the lid of a jar. Draw what you see 

in your eyepiece inside the circle. The best 

exercise for drawing is to observe the moons 

of Jupiter every night or so. Try to make 

Jupiter and the moons approximately the 

same size as they look in your eyepiece. 

You will see that the moons are in a different 

position every night. As you get better at 

drawing, try more challenging sights, like a 

crater system on the moon or even a nebula.
Go your library or check out the internet for 

more information about astronomy. Learn 

about the basics:  light years, orbits, star 

colors, how stars and planets are formed, 

red shift, the big bang, what are the different 

kinds of nebula, what are comets, asteroids 

and meteors and what is a black hole. The 

more you learn about astronomy, the more 

fun, and the more rewarding your telescope 

will become.

SOME OBSERVING TIPS

Eyepieces:  Always begin your observations 

using the 25mm low-power eyepiece. The 

25mm eyepiece delivers a bright, wide field 

of view and is the best to use for most 

viewing conditions. Use the high-power 9mm 

eyepiece to view details when observing 

the Moon and planets. If the image become 

fuzzy, switch back down to a lower power. 

Changing eyepieces changes the power or 

magnification of your telescope.
By the way, users of reflecting telescopes 

may have noticed something strange when 

looking through your eyepiece. The image 

is upside down and reversed. That means 

reading words can be a problem. But it has 

no affect on astronomical objects. 

Optional Accessory Barlow lens:  You can 

also change magnification by using a Barlow 

lens. The Barlow lens doubles the power of 

your telescope (See Fig. 10).
Meade offers a complete line of eyepieces for 

your telescope. Most astronomers have four 

or five low-power and high power eyepieces 

to view different objects and to cope with 

different viewing conditions.
Objects move in the eyepiece:  If you are 

observing an astronomical object (the 

Moon, a planet, star, etc.) you will notice 

that the object will begin to move slowly 

through the telescopic field of view. This 

STAR CHARTS

S

tar charts and planispheres are useful for a variety of 

reasons. In particular, they are a great aid in planning a 

night of celestial viewing.

A wide variety of star charts are available in books, 

in magazines, on the internet and on CD Roms. 

Meade offers AutoStar Suite

TM

 software. Contact your 

local Meade dealer or Meade’s Customer Service 

department for more information.

Astronomy and Sky and Telescope magazines print 

star charts each month for up-to-the-minute maps of 

the heavens.

Looking at or near the 

Sun

 will cause 

irreversable

 damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
