Now having the benefit of applying my equipment on a variety of stars I feel confident that the following challenge is well within my grasp (famous last words!) The question is: will my crappy northeast U.S. weather cooperate?
There is a star only 15 arc-minutes east of M27 the Dumbbell Nebula that is regularly eclipsed by an Exoplanet. The depth of the eclipse is a mere 0.0282 magnitude but fortunately the host star is a bright 7.67 magnitudes. This means short exposures! You don't want to over-expose the star. Ideally you want to bring it up to about 40,000 ADU. Don't go any higher or you risk saturation as it climbs in altitude.

Here is a link to a database where you can enter your latitude and longitude to find the next transit:
