Your telescope has a 700mm-focal-length objective and a 26-mm-focal-length eyepeice. One evening you decide to look at the full moon, which has an angular size of .52degrees when viewed with the naked eye.
A. What angle (in degrees) does the image of the moon subtend when you look at it through your telescope?
B. Suppose you decide to take a photograph of the moon using your telescope. You position film so that it caputures the image produced by the objective lens. What is the diameter of that image?
