We know, from observations of the M7 cluster, that the stellar images are not round across the field. This may because some of the optical components are not at right angles to the optical axos. I think that the color filters are angled slightly. We would like to map the ellipticity better and need more images – they should be rich in stars from side to side. Deep images of the Milky Way may be what we need.
