Abstract
We review the design, performance, and future prospects for the Hybrid Lyot Coronagraph (HLC) on the WFIRSTAFTA telescope. Together with a pair of deformable mirrors for active wavefront control, the HLC creates high contrast dark fields of view at 10-9 contrast levels, extending to within angular separations of 3 λ0/D from the central star, over spectral bandwidths of 10% or more.
