Title:Finding Tidal Tails of Star Clusters Abstract: Tidal tails of star clusters offer unique opportunities to determine and test the gravitational field of our Milky Way. Observations of those sparse and faint objects are difficult, though, due to their low surface brightness and large extent. Precise knowledge of their formation and evolution helps to minimise the necessary observing time and increase the detection rate. I will present recent results from N-body simulations and observations.
