We report on observations of transit events of the transiting planets XO-1b, TrES-1 and TrES-2 with a 25 cm telescope of the University Observatory Jena. With the help of all available transit times from literature including our own photometry our measurements allowed us to refine the estimate of the orbital period of all three transiting planets observed by us.
