Re: My first microscope

Hello...put one below the microscope stage..in the light path. To try the technique 'DIY', place the second polarizer filter right over the eye piece...rotate this polarizer as you look through the microscope. all the best, charlie Guevara/finger lakes,US

Re: 40X and 60X objectives

After this nice thread, I tested the Leitz Wetzlar/Germany Flour 63X objective..it works fine. If you are interested in both a 20X, and 63X objective, Crater Eddy ( have I enjoyed your postings a few years back, in: www.cloudynights.com ?!) ..if you are interested in both these 160 mm tube length ob...

Re: 40X and 60X objectives

Congrats ,Jim T on giving us a 'shoot out' between your 40X and 60X dry objectives..yes Dale will like his Plan objectives more so than achromatic objectives...they do cost more on a new microscope. I have a wonderful 'work horse' Nikon, Japan Plan 60X/0.85,160 tube length,0.11-0.23 ( a correction-c...

Re: Nov14-Dec14 issue...help!

Thanks for the assist, 'QCC', your shared link worked sweet! Err..should I always use such a direct link in the future, or was this just a 'glitch'?

Re: (Naked) Amoebas (video, ~7 min)

Wonderful DIC contrast of the streaming inclusions within those two beasts, Gekko, thank you! If that was simple specimen wetmount taken from their habitat..what a delightful encounter you imaged. Or did you set up that confrontation? With protists that large, you get a good idea what they eat,,,wel...

Re: Incident lighting on a budget

Congrats, mrsonchus! I am a terrific fan of low cost LED torches...I use them all the time at my microscopy bench. Is the image of those seeds with your 4X objective? Very crisp image. Being on the other side of the pond..I'm curious about your remark: 'Heath-'...does this equate with: 'quick and di...
