first time you go out at night.  Pick a night 

when the Moon is a crescent.  No shadows 

are seen during a full Moon, making it ap-

pear flat and uninteresting.  

Look for different features on the Moon.  The 

most obvious features are craters.  In fact 

you can see craters within craters.  Some 

craters have bright lines about them.  These 

are called rays and are the result of material 

thrown out of the crater when it was struck 

by a colliding object.  The dark areas on the 

Moon are called maria and are composed of 

lava from the period when the Moon still had 

volcanic activity.  You can also see mountain 

ranges and fault lines on the Moon.  

Use a neutral density filter (often called a 

“moon filter”) when observing the Moon.  

Neutral density filters are available from Me-

ade as an optional accessory and enhance 

contrast to improve your observation of lunar 

features. Spend several nights observing the 

Moon. Some nights, the Moon is so bright 

that it makes other objects in the sky difficult 

to see. These are nights that are excellent 

for lunar observation.

Observe the Solar System

:  After observing 

the Moon, you are ready to step up to the 

next level of observation, the planets.  

There are four planets that you can easily 

observe in your telescope:  Venus, Mars, 

Jupiter and Saturn.

Nine planets (maybe more!) travel in a fairly 

circular pattern around our Sun. Any system 

of planets orbiting one or more stars is called 

a solar system. Our Sun, by the way, is a 

single, yellow dwarf star. It is average as far 

as stars go and is a middle aged star.

Beyond the planets are clouds of comets, icy 

planetoids and other debris left over from the 

birth of our sun. Recently astronomers have 

found large objects in this area and they may 

increase the number of planets in our solar 

system.

The four planets closest to the Sun are rocky 

and are called the inner planets. Mercury, 

Venus, Earth and Mars comprise the inner 

planets. Venus and Mars can be easily seen 

in your telescope.

Venus is seen before dawn or after sunset, 

because it is close to the Sun. You can 

observe Venus going through crescent 

phases. But you cannot see any surface 

detail on Venus because it has a very 

thick atmosphere of gas.

When Mars is close to the Earth, you can 

see some details on Mars, and sometimes 

even Mars’ polar caps. But quite often, Mars 

is further away and just appears as a red dot 

with some dark lines crisscrossing it.

Jupiter, Saturn, Uranus, Neptune and Pluto 

comprise the outer planets. These planets, 

except for Pluto, are made mostly of gases 

and are sometimes called gas giants. If they
