Nice scope.
Does that condenser say achromat and/or aplanatic? Or just "1.4", which could be an Abbe. I have seen a B&L apo scope with plain Abbé 1.4 condenser, in person.
Have you tried delaying shutter release for >6 seconds and long exposure of about 2" or more? Most DSLR would work for mounted diatoms that way.

It says achromat. I could play with the delay etc by generally I tether it to my laptop and use the EOS utility. That eliminates most if not all blurring. However will try your suggestion once I get back my laptop. It is currently doing desk duty and is connected to a plethora of devices. I need to purchase a docking station to make it easier to move around. My wife absconded with my desktop for her sewing room.

Bausch & Lomb mfg. several 1.4 condensers up until they switched from a 160mm tube system to the common telescope lens/modified infinity system. A W.A. abbe type, and two achromat aplanats with differing focal lengths. There was a high N.A. quartz condenser too.
