The video was posted recently by Peter Evennett and it's very detailed, very practical and easy to follow for those who like to know how light paths travel and where it all goes and how it all works. An extremely informative, relaxed presentation.
Set aside an hour and enjoy.

Excellent video explaining the technical side of microscopy

Yep, he's an excellent tutor and shows things in a much more interactive fashion. Far better than a bunch of diagrams and talking heads. He goes into all the why's and wherefores and demonstrates exactly what should happen and why. It's the most comprehensive walk-through on the subject I've yet found and I've been looking everywhere.
Most only explain how, not why. He does a great job with both. Admittedly his setup is a lot more advanced than mine and I'm struggling to replicate it because mine is an old brass scope with a mirror and I'm building the light source for Köhler illumination myself. I can't center the condenser because it's not adjustable in that way, it only goes up and down so I'll need to get creative to make it work properly but I'm determined to make it work one way or another.
