We report follow-up observations of seven Kepler Objects of Interest (KOIs) from the remote controlled 0.61-m telescope at the Sierra Stars Observatory in California. We alternated between broadband photometric lters (NI-R-V-B) to measure transit events of KOIs it two distinct colors. We could then compare light curves (LCs) between lters in order to test for astrophysical false positive scenarios. Due to limitations directly resulting from the small aperture of the Sierra Stars Observatory telescope (SSOT) and magnitude of Kepler stars (between V15 and V18), LCs had a large root-mean-square (rms) scatter. In consequence, claims about the disposition of all seven KOIs lack statistical certainty in this study. However, change-point analysis (CPA) has proven to be an effective tool when parameterizing LCs. This technique has not been used before in exoplanetary transit LCs, and is worth comparing to other methods.
