What a difference a laser makes!

Caption: Narrow-field image of the Galactic Center at 3.8 microns (L prime) obtained with the Keck Laser Guide Star System on July 26, 2004 versus an image using the Keck Natural Guide Star System. Strehl ratio in the LGS image was measured at 75%, double the previous performance at this wavelength. A Strehl ratio of 100% represents a perfect, fully-corrected image. The resolution is 82 milliarcseconds, the equivalent of being able to distinguish a pair of headlights in New York while standing in Los Angeles.
