Abstract

The goal of much recent engineering improvements at the 3.5m WIYN telescope has been to improve imaging performance that utilizes the good intrinsic seeing at Kitt Peak. This direction complements the efforts of high order adaptive optics by maximizing the usable field. The new 'mini-mosaic' camera, which is a mosaic of 2 4K by 2K SITE CCDs is in the final stages of commissioning. With its 0.14 arc-sec per pixel scale at the Nasmyth f/6.3 focus, it is capable of adequately sampling the best delivered images from the telescope, while maintaining a relatively large field of view. We present some early performance results from this new instruments, and demonstrate the excellent image quality over the entire 9.6-minute field.
