APM 30mm Ultra Flat Field eyepiece

I bought a pair of these a few weeks ago for my binoscope however while they are indeed very sharp and flat field, they are a little too bulky in binoscope use.
(and it is better I sell the eyepiece than having a nose job )

The APM 30mm UFF is listed as having an AF0V of 70º but testing has shown that it is actually just under 73º. (38.2/30x57.3=72.9º)

focal length 30mm
eye relief is 22mm
eye lens is 32mm
field stop is 38.2mm
9 elements in 5 groups
2" only.

I bought Matt's other UFF30 and it's a very nice eyepiece - the view feels much like other ~70 degree high quality eyepieces (delos, Morpheus, etc) but in a 30mm focal length.
