　　The photometric accuracy of the time series produced by planet hunting space telescopes (i.e., Kepler and CoRot) proved to be 2 to 3 orders of magnitude better from the equivalent of ground-based observations. The profound reason for this discrepancy is the existence of the Earth's atmosphere and more specifically scintillation. We are using a sCMOS imaging camera mounted on the PTST telescope, which is located in the La Sagra observatory in Spain, in order to study the properties of scintillation noise with the goal to increase the accuracy of our instruments. Furthermore, with the first results of the nasa's TESS mission already available and the upcoming Cheops and Plato missions, it is clear the need for high accuracy follow up observations of bright stars. The unique characteristics of our setup allows for the application of differential photometry of very bright stars, a task which is almost impossible to achieve with the conventional CCD cameras.

　　As a proof of concept we present the systematic observations of the bright (-4.2 Vmag) delta scuti star eps-Cep.
