The stratus rarely gets used as it's performance is disappointing so it will probably get sold. The jump then from the 32 to 11 is pretty big. 46x to 136x.

The 16mm Stratus has about the same true field as the TV 32mm Plössl (about 50 minutes) and as such is probably not a good fit. Something with a field stop of about 15mm would be a good next stop, so the 11mm Nagler seems well placed. It gives you 34 minutes true field. If you want less magnification you could bridge the gap with an 18mm Radian (42 minutes true field, 83x).
