TeleVue Nagler6 5mm and Explore Scientific 82 Series 4.7mm are the only two that fits your requirements. All other have either smaller AFOV or larger AFOV.
Pentax SMC XW and Nikon NAV-SW are also excellent, but have smaller AFOV. Baader Morpheus is 76 degrees but 4.5mm is also outstanding eyepiece.
