This exercise is based on images of the globular cluster M4 taken with the telescope at Mt. Kent in Australia. Follow the links below for instructions, and access to the images and software. If you do not have a high speed connection at home, we can provide the images and software on a CD. Alternatively, the data and software are also available on the Physics and Astronomy computer system in Room 207. Please contact Prof. Kielkopf for help with these options.
