How to find the focal point for a telescope. The focal point is based on how far away an object is from the mirror.

The people in charge were nice. Their names were Liz who used to be a student and came to help with GEMS and Christy Dunn who is a professor at the university. This session was very interesting to go to. During the focal point experiment we used a Christmas light up Frosty the Snowman to substitute for a star. After this experiment we took prisms and look at sodium, hydrogen, and the fluorescent lights to see the different colors in the lights.
