The observed field of view on optical telescopes is often limited by detector size, and is smaller than the one available imaged by the telescope optics. This in turn constrains the number and quality of available calibration stars for each observed target. The Multi-Mirror Feed is an instrument intended for the MINERVA optical telescope, and is designed to make use of a large field of view even while constrained by a relatively small detector -- such as a CCD or PMT array. This increases the quantity and quality of available calibration stars while lowering the cost of the instrument. Wide fields of view are collapsed by selecting only the portions of the field which contain the target and calibration stars, using several small, moveable mirrors in the focal plane. This paper discusses the software developed to select these calibration stars using data from the Sloan Digital Sky Survey. The software will help optimize the performance of the MMF in both quality of data collected, and the observing time required to operate it.
