Talk abstract details

Open clusters are an ideal testbed for the calibration of stellar ages using gyrochronology. We used CoRoT to observe the open cluster IC4756. With its unprecedented photometric precision stellar activity amplitudes down to 0.03 magnitudes are observable. CoRoT observed the cluster for almost 73~days in LRc06, some targets were covered by the observing run LRc05. One target was identified as an eclipsing binary. First results of stellar ages in comparison with other studies as well as the underlying data reduction will be presented in this talk.
