Saturn, the second largest planet, is not as bright as Jupiter and so its moons are not as 
visible through small telescopes. The large rings that encircle Saturn are spectacular to 
observe, however. The planet and its rings appear pale yellow. The major division in the 
rings, the Cassini division, is possible to see if you keep the telescope firmly in position.  
 
Uranus and Neptune are the last of the solar system’s gas giants. They do not provide 
as spectacular a sight as Jupiter or Saturn, but are nonetheless rewarding to see. 
 
Beyond our solar system there are many more objects to be found. Galaxies, nebulae, 
and star clusters abound! 
 
 
FREQUENTLY ASKED QUESTIONS 
 
1) How far can I see? 
 
If you stand outside and look up at the night sky on a clear evening, you can see 
hundreds of stars without the aid of your telescope. The telescope is a light-gathering 
instrument that magnifies the view — providing significantly more detail and unveiling 
more stars, nebulae, and celestial objects. With the aid of a telescope, you will be able 
to enjoy exciting views of Saturn’s rings, Jupiter’s major moons, the Orion Nebula, and 
much more. 
 
2) Why can’t I see anything through my telescope? 
 
If you see only gray or black when looking through your telescope, even after searching 
for an object to view, it is very likely that you are using an eyepiece that is too powerful. 
To solve this problem always start with the lowest power eyepiece first, and only insert 
the higher-power eyepiece after you have located an object. 
 
3) When I use my high-power eyepiece, everything looks much darker. Why? 
 
As magnification in a telescope increases, brightness diminishes. Conversely, 
brightness increases when magnification is reduced. If an image appears too dark or 
unclear, use a lower-powered eyepiece. Views of small, bright objects are superior to 
those of large, dark, or blurry ones! Atmospheric conditions, air currents, as well as light 
and air pollution also affect viewing quality. 
 
4) As I look through my telescope, objects in the sky appear to move. Why is 
that?
 
 
The constant rotation of the Earth makes things appear to move. Lower-power 
eyepieces will reduce this effect of movement considerably and allow you to observe an 
object for a longer duration before you have to readjust your telescope.
