30mm Superview will do better than the 32mm RKE. afaik the QX is not much better just lot more expensive. Anything over 30mm is for use by young astronomers under dark skies only (due to exit pupil > 6mm). 60 degree Meade 5000 plossls, 26 or 32mm, are good value and work quite well at f5 (better than the superview; coma from the mirror is the main issue but that's going to be there with any EP).
