My first attempt to measure the transit of an exoplanet was on a night with poor seeing and a full moon. Wasp-50b is a hot jupiter orbiting a 11.55 mag star. If you use your imagination you can see a depth of around 20 milimags & transit time of 108 min. which agrees with other observations. The blue line represents a comparison star that was fluctuating at +/- 10 milimags due to poor seeing conditions.

Wow, Jim, this is amazing. Seems like you really need that AO in order to get meaningful data around here, though.
