Questions 1. After introducing the different common types of telescopes (reectors, refractors, and catadioptrics), we discussed three main powers of telescopes. What are they? 2. Look at the binoculars illustrated below, labelled Set A, B, C, and D. What is the highest magnication power of the four sets displayed? (Hint: give the magnication, not the letter for the set.) 3. Of the four sets of binoculars illustrated in this assignment, which setA, B, C, and D has the most light gathering power? 4. Assuming your eye has an aperture of approximately 5 mm, what is the light gathering power of binoculars set C, compared to your eye? (Hint: your answer should be somewhere between 90 and 160.) 5. What kind of telescope uses a large lens as the objective to gather light? A reector, a refractor, or a catadioptric (such as a Cassegrain)? For the following set of questions, suppose you had three telescopes, each with an eyepiece. Telescope A has an objective lens with diameter of 75 mm, focal length of 1200 mm, and an eyepiece of focal length 9 mm. Telescope B has an objective mirror with an aperture of 150 mm, focal length of 750 mm, and eyepiece of focal length 40 mm. Telescope C is a catadioptric with an objective diameter of 200 mm, focal length of 2000 mm, and an eyepiece of focal length 15 mm. 6. Which telescope, A, B, or C, is the refracting telescope? 7. What magnication would you get with telescope B? (Hint: your answer should be somewhere between 7 and 35.) 8. Two parts--answer both, in order. a. What is the light gathering power of telescope C compared to telescope A? (Hint: your answer should be somewhere between 2 and 9.) b. What is the light gathering power of telescope B compared to one of the lenses of binoculars set D? (Hint: your answer should be somewhere between 11 and 35.) 9. Two parts--answer both parts. Suppose you were observing with telescope C with an eyepiece that has a focal length of 15 mm. a. What is the maximum practical magnification you would expect from this telescope with that eyepiece? (Hint: your answer should be somewhere between 280 and 570.) b. Suppose you had three new eyepieces you were considering using. The focal lengths of the eyepieces are as follows. Eyepiece #1: 55 mm Eyepiece #2: 25 mm Eyepiece #3: 4.5 mm Which eyepiece would be a BAD choice for you to use? (Hint: Consider your result from the first part of this question.) 10.Consider all four eyepieces that we used for telescope C (55, 25, 15, 4.5 mm). Which of these four eyepieces would provide the widest eld of view, if we used them with telescope C? (Specify the eyepiece using the value of the focal length - don't just give the eyepiece stated as #1, #2, #3, or #4)
