Observations were obtained at the WIYN 3.5m Telescope at Kitt Peak National Observatory during the time interval from 2007 January to 2008 June. In all cases, the relative separation and position angle of the components are measured, and the magnitude difference is determined in 809 cases. The precision of the results as judged from repeat observations and objects with very well-determined orbits is similar to previous papers in this series, namely ∼3mas in separation and <1° in position angle in most cases. Similarly, the photometric precision remains consistent with previous WIYN speckle data, on average ∼0.1mag per observation. Six systems of special interest are discussed. Description: All of the observations discussed below were obtained at the WIYN 3.5m Telescope, located at Kitt Peak National Observatory. We present results from six observing runs that occurred between 2007 January and 2008 June, where the instrumentation used was the RYTSI speckle camera and one of the two PIXIS 2048B CCDs now used in the DSSI.
