If you go to 2", then and excellent choice is the 31 mm Nagler with 82 degrees AFOV and 1.7 degrees TFOV at 49x mag.

That eyepiece is probably worth almost as much as the 5" mak. Unlike fast F-ratio newtonians, with scopes like a 5"/f12 MCT it isnt necessary to buy the absolute cream of eyepieces to get decent performance. In a scope like that the Japanese made 30mm University Optiks MK-80 will do almost as well as the 31mm Nagler for less than 1/4 of the price and for about 40% of the cost of the 31mm Nagler the ES 30mm 82 deg will do very nicely in an F12 MCT.
