What are special parts of the astronomical telescope?
KELLY, AGE 14, CHARLTON Answer: There are two common types of astronomical telescopes. A refracting telescope, like the ones you see sailors using. They have a lens at one end and an eyepiece (which is just a collection of other lenses) at the other end. This is all held together in a tube. So the light passes through the main lens, down the tube, through the eyepiece and into your eye. The other type of telescope is the reflecting type. It uses mirrors instead of a lens. At the bottom of the tube is a large round mirror, at the top of the tube is a smaller flat mirror set at an angle and then an eyepiece on the side. The light from a star falls down the tube, hits the big round mirror, bounces back up the tube and hits the second smaller flat mirror which sends the light out the side of the tube into the eyepiece and into your eye. The reflecting telescopes are cheaper and much more popular for astronomy. Which constellation is Polaris in? SARAH, COLLINGWOOD Answer: The star Polaris,
