The University of Hawaii 2.2 Meter Fast Tip‐Tilt Secondary System

Year: 2000

Type: article

Abstract: 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.
