The whole problem with longer FL mirrors is the inability to see the surface
at that long of a distance.  The cure for it is to us a telescope directly
behind the KE (makes finding the mirror a bit more difficult as you also
need to match the height of the return image on the KE) like a small finder
scope to see the mirror (focus on the mirror!) fill the eye more than the
regular size image.  If you're already using a TV camera behind the KE then
it just means that you need a longer FL lens to see the mirror better.
