Observing Exoplanet Transits

For the last few years, I've been attending the Imaging the Sky Conference in Portland Oregon - a really great local astro-imaging meeting. One of the regular speakers is Ken Hose from Wilsonville, OR, and for the last 2 years he has given a presentation on Observing Exoplanet Transits. The topic really caught my interest, and this year I finally got around to observing some transits from Southern Oregon.  With the help of Ken's presentation material, and a number of emails back and forth, I was able to observe and process 3 transits with pretty good results.

Exoplanet transits are really fun and challenging, and a good alternative to imaging for those nights with poorer seeing or too much interference from the moon for really good imaging. Best of all, you can submit your data to the Exoplanet Transit Database, and make at least a minor contribution to exoplanet science. In fact, the Exoplanet Transit Database is the place to start, as it will give accurate predictions of transits that will be observeable from your location.

Here are my published results for TrES-3 b, as shown on the ETD website:
