At the left is the "Lucky Imaging" system's view of the globular star cluster M13. At the right is the Hubble Space Telescope Advanced Camera for Survey's view of the same cluster. The black band is a gap between sensors (and misses the two bright stars). The clarity and resolution of the "Lucky" image surpasses Hubble's abilities, although Hubble's can consistently take longer exposures and obtain "deeper" images of the universe.
