Abstract:                               ! Free format text (clear and concise)
We are continuing our study of the initial mass function of intermediate
mass stars in nearby clusters. The object chosen here is a young populous 
cluster, but it is not as concentrated as R136. Therefore, it will provide
an interesting comparison to our earlier work on the stellar population in
the more crowded R136 cluster.

    Observing_Description:
The exposures are a series through F336W, F555W, and F814W.
They are intended to go as deep as we have time for but without
washing out the center of the cluster with saturated stars in any one image. 
The multiple images also allow for removal of cosmic rays.
