Abstract (from CDS):
Using a new f/31 secondary on a tip-tilt platform, we have built an image-stabilization system which has been used regularly for astronomical imaging and spectroscopy on the University of Hawaii 2.2 m telescope. Diffraction-limited cores of stellar point-spread functions are achieved in near-infrared imaging, with Strehl ratios as high as 0.47. K-band images with 0".3 FWHM 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.
