We present transit light curves for the exoplanet systems XO-2, WASP-2 and TrES3, observed using the AGILE camera on the 3.5m ARC telescope at Apache Point Observatory (APO). These data are part of the larger transit timing campaign named APOSTLE. AGILE is a frame-transfer CCD camera, which allows us to observe transits at a 100% duty cycle, avoiding photon loss during readout. We discuss the trade-offs between observing in and out of focus, varying our exposure times, and observing in different passbands. Comparing data from various observing modes has brought us closer to a strategy that provides optimal signal-to-noise light curves.
