Laser Guide Star Images of the Galactic Center
Caption:
The Laser Guide Star Adaptive Optics System at the W. M. Keck Observatory takes infrared images of the Galactic Center. The image above is taken in the L'-band (3.8 microns), is 10 arcseconds in size and has a resolution of 82 milliarcseconds. At 3.8 microns, the Strehl ratio was measured at 75%, double the previous performance at this wavelength. A Strehl ratio of 100% represents a perfect, fully-corrected image. At K' (2.1 microns) the Strehl ratio was measured at 35%, a modest improvement, and the resolution was 56 milliarcseconds.

He I (1.43 micron) and K_continuum (2.29 micron) two-color mosaic image
This image is 80" x 80" and was created from only five pointings of the telescope in each filter and consumed just 20 minutes of telescope time. The LGS-AO system allowed the artificial guide star to be positioned at the center of each pointing.
