Astronomy 101 Online Summer 2007 - Alternate Observing Project There's nothing quite like being able to look through a telescope at a distant object in the night sky. As you would imagine, the project you are about to do is not really a suitable replacement for that experience, but we'll have to make the best of it. For this project, you'll be doing some observing in Starry Night, as you would have done if you were out at Atwood. Start by setting Starry Night to the following conditions: Date: 7/6/2007 Time: 9:30 PM Daylight Time Time Flow: Frozen (hit the stop button) Viewing Location: Champaign (or Urbana, if you don't have a Champaign entry) Now get yourself oriented. Since the sky isn't quite dark yet on the program, go into the View window and select "Hide Daylight". Without any labels on, see if you can find the Big Dipper and Polaris. If you can't, it's okay to turn on labels to help you out. If you want to turn on the drawing for the Big Dipper, you'll need to go into the "View" menu and select "Constellations -> Asterisms" and "Constellations -> Labels". 1) When facing Polaris, is the Big Dipper to the right or left of Polaris? To the left 2) Find the star Dubhe in the bowl of the Big Dipper. Double click on it to open the info window. What is Dubhe's right ascension and declination? 11h 4.21m 61d 42.615’ 3) Scroll around the sky to find the Milky Way. Where does the Milky Way meet the horizon? Express your answer in terms of the cardinal points. Remember that it will cross the horizon at two points. It crosses at south and north Under the "View" menu, select "Constellations -> Boundaries", "Constellations -> Labels" (if you haven't already turned them on), and "Constellations -> Astronomical". The constellation stick figures should now appear along with the constellation names and boundary lines. If you don't know the constellations of the zodiac, you will want to refer to "Table 1-1" on page 21 of your textbook. 4) Which constellation of the zodiac is now setting in the west? Cancer 5) Which constellation of the zodiac is now rising in the east? Sagittarius It's time to let the real observing begin. There is a wonderful catalog of deep sky objects that you can see with a pair of binoculars or a small telescope. This catalog is called the Messier catalog and is included within Starry Night. Under the Labels menu, turn on "Messier Objects". You will
