Abstract
We study the structural properties of the compact stellar cluster population in M81 using the HST/ACS images in the filters F435W, F606W and F814W, that cover the entire optical extent of the galaxy. This population contains 263 young compact clusters as well as 172 old globular clusters. In this work, we analyzed the size distribution of the young compact star clusters and globular clusters in M81 and compared the latter with that of the Milky Way.
