Abstract

We present preliminary observational results of the multi-site STEPHI campaign on the cluster NGC 1817. The three observatories involved are San Pedro Mártir (Mexico), Xing Long (China) and the Observatorio del Teide (Spain) --- giving an ideal combination to maximise the duty cycle. The cluster has 12 known delta Scuti stars and at least two detached eclipsing binary systems. This combination of characteristics is ideal for extracting information about global parameters of the targets, which will in turn impose strict constraints on the stellar models. This then allows us to use the observed pulsation frequencies to learn about the physical interior of the pulsating stars.
