    How a telescope works. A refractor is like a larger version of a seafarer's spyglass. It has a long tube with a main lens at one end to collect and focus light, and an eyepiece to magnify the resulting image. In the traditional Newtonian reflector the light focused by the primary mirror is bounced back up the tube to a small secondary mirror which diverts it into the eyepiece.

The corrections are made faster than the atmosphere can change -- thousands of times per second. Mona Evans, "Palomar Observatory" www.bellaonline.c...

Great idea to use the telescope to show what we might see in space. Adding the writing would be great for older primary students!
