4) As I look through my telescope, objects in the sky appear to move. Why is 
that?

 

 
When you observe an astronomical subject through a telescope, the constant rotation of 
the Earth makes things appear as though they are moving across the viewing area. The 
equatorial mount provided with your telescope compensates for this by moving the main 
optical tube in a circular fashion, allowing you to follow and study celestial objects with a 
minumium of manual adjusting. If you would like to reduce this effect of movement to a 
minimum and observe the widest field of view, you should use lower-power eyepieces.
