PH 325 - Experimental Astrophysics
Fall Term of 1999

The pictures shown below were taken by students taking this course.  Starting at about 9:00 pm, all seven members of the class used 35 mm cameras, Tri-X film, tripods, and stopwatches to obtain pictures of long star trails and to take pictures of several constellations.  They develop their own film and make prints using the department's darkroom.

These photos were taken with an ST-6 CCD camera and an 8" telescope
 in rural Milan on September 29, 1999.
