This is a program to obtain wide field imaging around a set of high redshift clusters. The goal is to obtain 1h in I, 2h in R, and 1h in V to look for structures surrounding the clusters which could be associated with the clusters. The major observing constraints are that program needs to be able to distinguish z=0.5-0.9 galaxies from stars, so need seeing better than 1.2", the typical size of giant ellipticals for these clusters. The R-band is requested at better than 1.0". ! Critical Observing Condition: Observe the R-band OB's with as small a PSF as possible. This program requested for both twilight and dome flats to produce the best nightsky flats. This program is allowed to use OBs longer than 1h.
