The RYTSI speckle camera, completed in 2001 and currently located at the WIYN Observatory at Kitt Peak, is a device that allows speckle images to be recorded on any large-format CCD device. It uses a two-axis galvanometric scanning mirror system to move the location of the target in a serpentine step-and-stop pattern, thus building up a sequence of speckle images that covers the CCD chip prior to full-frame readout. In February of 2004, the RYTSI device was combined with the Kitt Peak Mini-Mosaic imager for speckle observations at the WIYN 3.5 m Telescope. The mechanics and successes of that observing run are reported, including some diffraction-limited image reconstructions of binary stars. Estimates of the capabilities of the RYTSI/Mini-Mosaic combination based on this experience are also discussed. This work is funded by NSF Grant AST-0307450.
The WIYN Telescope is a joint facility of the University of Wisconsin-Madison,Indiana University, Yale University, and the National Optical Astronomy Observatories.
