Was there an earthquake at Caltech...

...or is this the design someone chose for the new Cahill Center for Astronomy and Astrophysics?

More Fuzzy Objects

Student observations of nearby galaxies for my astronomy class' final project followed by images from various big telescopes for comparison (the color images were not taken by my students). Instrument: Meade LX-200 16" reflecting telescope with Schmidt-Cassegrain optics and an SBIG-7 CCD camera. Image data were collected and reduced using the CCDSoft software application for Windows.
