Dust clouds within globular clusters

We present the results of a CCD survey of ten southern globular clusters. Image processing shows the existence of dark regions which may be the results of the presence of dust clouds. The behaviour of these cloud candidates in the BVRI bands can be explained as the result of the combination of geome...
