Title:  CCD Photometry from Inside the Light Dome – Leisure Time Activity for a Retired Engineer

Presenter:  Tom Polakis became an amateur astronomer on the night of the 1977 Perseid meteor shower.  He is a Contributing Editor for Astronomy Magazine. His main interests are astronomical travel, visual observing, and all types of photography.

In the past few years, Tom has actively pursued photometry with his CCD imaging equipment in Tempe.  During that time, he has determined rotation periods of asteroids, measured brightness and colors of eclipsing binary and pulsating variable stars, and created light curves of exoplanets and an active quasar along the way.  During the first half of Tom’s presentation, he will describe the fundamentals of photometry, his equipment and acquisition of images, and data reduction.  Then Tom will show examples of  his work to illustrate how measuring something as simple as the variation of light and color teaches us much about stellar and solar system astronomy.

At the January meeting Doug Smith will discuss “Variable Stars”. The “Constellation of the Month” is Perseus, presented by Jim Schrode.
