The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.

This lab is designed to familiarize students with the technique of photoelectric filter photometry and counting statistics. The software for this exercise puts students in control of a computer-controlled telescope with sidereal tracking. It illustrates the use of equatorial coordinates for finding stars in a cluster and introduces the use of H-R diagrams for analyzing the age and distance of clusters. A student guide supplied with the software describes how to use B and V photometry of cluster members to plot an H-R diagram of the Pleiades and to determine its distance. This is part of a larger collection of simulations, Project CLEA.
Please note that this resource requires
at least version 95 of MS-Windows.
