Photometric Filters Activity

A detailed activity for demonstrating how filters are used for photometric measurements will be posted up here shortly. In the meantime many Physics texts provide such investigations so check your textbook.

A very useful software-based activity is Project CLEA's The Photoelectric Photometry of the Pleiades. It allows you to simulate control of a telescope to obtain photometric readings at different wavebands for the Pleiades open cluster. It is free software package for WinPCs that can be downloaded from the site. An extensive User guide and an excellent student book can also be downloaded.
