Peter,
Most of Tak's OTA's with 4" focussers have wide flat fields if used with their respective flatteners, I had the FSQ106 in mind but also the TOA150, I guess TOA130, some of the Epsilons, Greg can comment on BRC's etc

Greg can also comment on the TEC refractor he's got.. I'd imagine the TEC180FL would have a fairly large corrected imaging circle...
