Re: What's German for "a few of my favorite things?"

There's no way not to love something with so many knobs, dials and twiddly bits. It is a thing of beauty, especially to an engineer! Like you, I'd want it just to have it.

You're really getting the hang of this 'make awesome' routine :D
Do you reset the camera white balance for the green filter? I'm still trying to get my noggin around this whole process.

Re: How is this not DIC? Oblique illumination? HOW?

I subscribed to his channel a while back. He manages some remarkable depth and if it is oblique, I have no idea how he manages to achieve that look. I've tried a bazillion oblique techniques and none are close to his.
I'd love to know what he does.

Re: Super Glue 3 weeks Colored bubbles

That's odd, I've used superglue to make permanent slides and it's been flawless. I used the thin version that wicks like water and works well for many things as a quick prep. I'm kinda sad mine didn't look as interesting as yours.

Welcome, and yes, fixing up old scopes is a lot of fun. I even 'fix' my non broken stuff (bad tinkerer habit). I have at two scopes in a constant state of disrepair that I'm always messing with because.. reasons 8-)

American Optical head fits Zeiss?

Hey all, this may seem like a daft question, but do the AO heads fit Zeiss standards? I ask because I've seen these for sale attached to a Zeiss dual head block like the one below. If this is the case, is the AO head standard 160mm-ish or is it an infinity head. I ask because my spare Zeiss frame is...

One of these days I plan on adding a vertical/epi illuminator to my lomo but one thing I noticed is that a lot of the good 'reflected light' objectives are infinity corrected and I don't recall seeing anything about how to make use of these on lomo microscopes. Is this something only available on hi...

The phase isn't as pronounced with fully transparent subjects, I think my phase rings are a bit too small and too 'made of ink' to be ideal. It still works better than the Jena objective though.
