[76.05] A Fast Tip-tilt System for the University of Hawaii 88-inch Telescope

K. T. C. Jim (IFA, U. Hawaii)

Using a new f/31 secondary on a tip-tilt platform, the University of Hawaii has built an image stabilization system which has been used regularly for astronomical imaging and spectroscopy. Diffraction-limited cores of stellar point spread functions are achieved in near infrared imaging, with Strehl ratios as high as 0.47. Deep K-band images with 0.3 arcsec resolution (without deconvolution) are routinely obtained. The construction, operation, and capability of the current system are described, a summary of recent scientific findings is presented, and future improvements are outlined.
