A Scout-class explorer mission capable of studying evolution and structures on the largest scales in the universe is described. It is argued that the presently planned instruments have limitations that are not related to collecting area but are caused by a limited field of view. From galaxy cluster studies by Burg et al. (1989) and Cavaliere, Burg, and Giacconi (1989), it is concluded that the luminosity function at the current epoch is not sufficient to disentangle the various contributions of cosmology (the density fluctuation spectrum) and astrophysics (structural evolution and gas injection). An optimizing ray tracing code is derived where the solid angle weight point response function was minimized over the desired field of view. The design of a telescope which has an angular resolution of better than 2.5 arcsec rms when averaged over a 30-arcmin-radius field of view is presented.
