The HST/ACS Legacy Survey on the Coma Cluster
The HST/ACS Treasury Survey on the Coma cluster used the ACS camera onboard HST to image two regions of the cluster in two filters, F814W and F475W. 29 pointings were completed before ACS failed in January 2007. The project is described at the Coma website.
Check out some of the beautiful HST/ACS images, and the Coma Skywalker, at http://astronomy.swin.edu.au/coma/image-gallery.htm#.
Within the collaboration, I lead a working group for the derivation of structural parameters. The group's mission is to derive catalogs, photometry and structural parameters such as size, surface brightness, shape, bulge-disk-nuclear component decomposition.
Here is another example of a cutout of the Coma imaging survey.
