Re: Onion stoma using Canon EOS 1200D

The 60x onion image is good but I see more detail in the 40X. Too much enlargement??? Nice camera. How have you mounted it? I agree, but the 60x is very sensitive to mount quality and the proximity of specimen to underside of coverglass, also the refractive index of the mounting medium and the over...

Re: 40X and 60X objectives

Nice comparison! I have often thought about getting a 60x objective, and a 20x as well. Darned Ebay sellers aren't cooperating though. :lol: CE Hi, I have a 5-objective 'scope with a 4x, 20x, 40x, 60x (dry) and 100x (oil) - I asked for the 10x to be replaced with the 60x when I bought the 'scope - ...

Hi, add some Fuschin until it's a strong vivid red (this will take less that you think) to the 96% alcohol.

Re: A couple more human blood photos.

Thank you! And, as expected, the clear nail polish is not suitable, as it caused much of the stain to migrate to the edges of the cover slip. It was quite interesting to watch. Also, the glycerin is having a similar effect, though not as pronounced and in much slower motion. CE These are really goo...
