In this paper, we discuss solar coelostats and heliostats and their alignment, with special attention to setting up portable heliostats at eclipse and other field sites. We consider the sources of tracking errors and the relation of small misalignments with such tracking errors. We consider the relative advantages of coelostats and heliostats.
