Re: Ciliate frenzy.

I agree DonSchaeffer -I reckon dark field picks up bacteria at lower mags better than phase contrast even-especially if you just want to quantify bacterial activity in soil or compost-I can often see it at 4x even-though it’s more of a shimmering unless it’s a really sharp 4x like a fluorite or Apoc...

Re: First images with new camera

Nice work particularly the dark field-what camera is it model wise and do you know how many FPS it can do in video? A lot of microscope cameras have disappointing frame rates (ie 10 or 15fps) too slow to keep up with action scenes..

You won’t regret getting a 20x-it could take the space of the (for a lot of people) rarely used 100x-you miss a lot of interesting details jumping between 10x to 40-never understood why cheaper scope makers bother with the 100x but miss the 20x as oil immersion is tricky and messy and if there only ...
