Suppose I want to observe the two binary stars Mizar and Alcor. An example image is seen in the figure. I have decided to use the refracting telescope at the Yerkes Observatory, which has an objective lens with a diameter of 1.00-m and a focal length of 2.50 cm. My observations will be in visible light. a. Draw a rough ray diagram for this telescope. Label the distances. (The drawing does not have to be to scale.) b. If the above figure shows how the stars appear in the sky, what would the resulting image from the telescope look like? Draw a rough sketch. c. What are some effects that lead to distortion in the final image? How could I avoid this distortion? d. Yerkes Observatory has the largest refracting telescope in the world. Why aren’t there larger refracting telescopes? Name two reasons.
