Testing a new illumination technique with my favorite AO 1.25 Abbe condenser, converted for Nikon. It is something similar to the mix of the Hoffman/Goerz condenser, but with some adds (will post later). Will make the same adaptation for the my universal condenser conversion kit also - works pretty interesting and it is a flexible thing ...
