AST 1022 Telescope II Worksheet Name: Lab Partners: Grade: 1: Make a simple sketch the light path of a Refracting Telescope (You'll ned to look this up somewhere). Label the Objective Lens. 2: Make a simple sketch the light path of a ReFecting Telescope. Label the Primary Mirror. 3: Thanks to Astro Lab, you have become a world famous astronomer and have decided to develop a new scale to measure the apparent brightness of stars. Explain your system and give examples. (Be creative!) 1

AST 1022 Telescope II Worksheet Name: 4: What is the formula for magniFcation? Calculate the magniFcation for a telescope with a focal length of 3050 mm used with a 16 mm eyepiece. 5: You decide to buy you own refracting telescope and for your budget you can buy 3 inch (aperture) advertised with 1000X magniFcation or a 5 inch advertised with 400X magniFcation. Which is the better deal and why? (Hint you can always get different

Magnitude Aperture 1 2 3 4 5 6 2 AST 1022 Telescope II Worksheet Name: 7: Attach a plot of your data. 8: At its brightest Mars has a magnitude of -2. How many times brighter is this than a 1 st magnitude star. (Hint: Use the table on page 4.2) 9: The 30-inch A.G. Smith Telescope at UF's Rosemary Hill Observatory has an aperture of 76 cm. Your eye has an aperture of about 8 mm. How many times more light can the telescope gather compared to you eye? (Remember light gathering power is directly proportional to area [ area = (pi * aperture^2)/4 ] so you should compare them as a ratio, resist the urge to subtract!) 10: The small telescope at RHO has an aperture of 18-inches. What is the faintest magnitude you'd expect to see? (You can read this directly from the table on page 4.2) 11: What are some sources of error in this experiment? 3...
