A little while ago on SAA, Roland Christen mentioned building eyepieces
with a tiltable element to correct for the chromatic smear when viewing an
object low on the horizon.

Would you get the same correction with a refractor by taking the diagonal
and setting a set screw at one end to slightly tilt the mirror so as to
have the same effect as slightly tilting the eyepiece?
