I'll need to add my new Prostars to the database. They are sharp, but not yet measured.
The best of the best that I've measured
Fujinon FMT-SX 16x70
Pentax PCF WP 16x60
Nikon SE 12x50
Fujinon FMT-SX 10x70
Fujinon FMT-SX 10x50
Celestron Regal 8x42 Roof
Nikon SE 8x32
Oberwerk Mariner 7x50
In the above group, at the very edge, the finest is the Nikon SE 12x50
5% to 10% in from the edge, the best, in this order, are the Celestron Regal 8x42 Roof, Nikon SE 12x50, Nikon SE 8x32, Fujinon FMT-SX 10x50. The Fujinon FMT-SX10x50 do it with an astonishing 70° Afov, the FMT-SX 16x70 with an Afov=65°.
None of the above even come close to these combos
Oberwerk BT100 - 20TV pl
Oberwerk BT100 - 14 Radian
Oberwerk BT100 - 12.5 UO or
In the BT100, with the 14mm Radian, I observed a 5 arcsec double star split even as it drifted off the very edge of the field stop, a total edge aberration only 1/3rd that of the Nikon SE.
