Hi Alex,

The fly in your ointment is that binocular objectives are designed to work with the prisms in the optical train. The lengthy glass path in the prisms adds spherical aberration. If you remove the prisms the objectives will be less than sharp.

Better to buy a bunch of small APO objectives and assemble the rest yourself, but they'll cost rather more by the time you're done.
