The imaging of faint planets near bright stars requires the development of high-contrast detection techniques, and we have been developing both of the necessary aspects - precise wavefront control and small IWA coronagraphs - for use on our extreme adaptive optics (ExAO) level "well-corrected subaperture” on the Palomar Hale telescope. Specifically, we have implemented the modified Gerchberg-Saxton algorithm to reduce non-common path speckles, have employed the locally optimized combination of images (LOCI) algorithm for point spread function subtraction, have implemented upgrades to the post-AO pointing and focus to stably center the starlight on our coronagraphic masks, and have implemented a vector vortex coronagraph to reach very small inner working angles. Using our upgraded system, we have recently imaged all three of HR8799's planets with a telescope subaperture only 1.5 m in diameter. Our detections illustrate the importance of all of the enabling technical advances, and also highlight the promise of future high-contrast ExAO systems, both on the ground and in space.
