Leitz Leica objectives advice

Does anyone know about the leitz UTK P (strain free) objectives with irises? I’ve noticed one is 32x/.40 P but underneath that writing is 50/.63-can it extend or something to manage both magnifications? I find the way leitz/Leica objectives are categorised to be confusing (same with numbers on conde...

Re: Three Ameobas

Those amoeba are breaking social distancing! I’ve seen amoebae pass through each other like ghosts-I’ve read somewhere that an amoebae having trouble dividing can have a “midwife” amoeba arrive and sort of push the daughter cells apart. They hold many mysteries and I think we underestimate their abi...

Re: Labeled Amoeba Pictures

My two cents-I’ve noticed when using some quite low N/A (ie 40x n/a 0.5) inverted objectives the extra depth of focus allows one to notice that amoebae do move in 3-d.sometimes flat against the slide,sometimes reaching up to grab something above it and sometimes just letting go of the slide altogeth...

Phase turret question

I’ve noticed on various phase turrets from different makers a big range in N/A-most seem to be 1.25 or 1.30 but I’ve seen a Nikon one down to .85-these are upright phase turrets-what’s the effect of such a difference in turret N/A to image quality?

Curious-can older short barrel Olympus objectives be used on a CH-2 (with CH-1 eyepiece/photoeyepiece) or does the stage not come up close enough to be focused?

Re: I call them bell gliders

Good clues Bruce Taylor-thanks-I think the middle flagella is longer than the other structures-I will endeavour to catch them on video rather than just rely on memory-they do always seem to swim in a joined line like in the sketch.

Oh better clarify my Olympus is a BH-1- I know the BH-2 has an AA condenser but I’m not 100% sure if you can de-center it cos of the different condenser mount on the BH-2. I’m sure someone will clarify for you.
