Thanks for the advice
I was hoping for crazy wide-field, like your binocs Brent.
Rigel003, I had not even considered exit pupil, and you're right, the 42mm would be a waste -- the wrong EP for the scope.
Might consider the 30mm Superview, otherwise stick with our current 17mm (75x magnification and 3.4mm exit pupil).
Learnt something - thanks again
