			If you submitted a request for data, we have tried to get it for you this semester. In some cases the requests could not be met because the objects were too bright (a very bright star for example), or too close to the Sun to view at this time. Also requests for objects in the solar system would usually duplicate our scheduled recording of the bright planets and asteroids. For these lab activities we have combined our most recent data in the archive indexed by object name, and dates. You can access any data in the archive by following the link given above.

	~~Now that~~ you ~~have the software~~ and the data, you are ~~probably wondering~~ what ~~to do with it~~.		Look at what is available, think about what you asked for, and decide what question you want to explore. If you did not submit a request, or if the data you hoped for are not available, think over the possibilities, pose a new question, and use what you have.

It will be quite different from the pretty pictures you may get from the Hubble Telescope or press releases from ESO.

	In NGC 7662, what 3-dimensional shape could make the object look like this? There are images taken in filters isolating light from hydrogen, sulfur, and oxygen. Is there a difference in where these features appear in the nebula? Measure how large NGC 7662 is in diameter on the sky (an angle), and look up its distance with help from Google. See if you can figure out how large in diameter it must be compared to our solar system. (Your assistant may help if you get stuck.)

For the Pleiades, Messier 45, how would you decide the distance to the stars, and how will that distance affect their appearance in the images?

	For the Moon, look for famous named craters. Find Copernicus, Tycho, Plato, Mare Imbrium, the lunar Appenines, and Sinus Iridum. How big are they? That is, how many kilometers across are they? Why are shadows longer for craters and mountains close to the "terminator", the line that divides the light and dark sides. Are the craters that are near the top or bottom (north or south) really oval, and if not, why do they appear to be oval? How did the floor of Mare Imbrium or of Plato become so free of craters? Find other images of the Moon on the web and compare them to this one. Can you see more or less of the Moon toward the edges of the disk? Why is that?		For the Moon, look for famous named craters.
