That would be great if it did, wouldn't it!

400x is perfect for counting in a counting chamber, so the magnification is plenty. All the nice features there make it look like the greatest deal ever seen in microscopy. Unfortunately, you know what they say about deals "too good to be true".

Those who seem to know about these kinds of things say that scopes like these are a waste of money because the optics are crap and only result in frustration. But if I were you I'd try get a live demo on one of those things, dial it to 400x (40x objective), and ask yourself if you could clearly resolve yeast cells on that screen. The screen resolution is going to GREATLY affect the usefulness of that scope.

They list a mechanical stage, which presumably allows you controls in X and Y, but at magnfication it might not give smooth movement and fine-enough adjustment to be useful. This would another thing to check.

I'm sceptical, but for $200 I'd absolutely buy one if it even barely worked. Besides, with the digital photo/video, it would also save you from the kludge I've been using to get pics of the cells.

passedpawn, if you're taking requests for your "to do" list, could you count the number of cells in a bottle conditioned beer - say a Bell's Amber or Pale Ale?

BTW, PassedPawn, if I buy a traditional microsope (as opposed to that LCD one I just asked you about) I was considering this as an add on.

Amazon.com: Celestron Digital Microscope Imager: Industrial & Scientific

This may not be high enough MP for you, but thought I'd pass it along. At the lower magnification (40x included), people are saying it does a decent job...

All right. I'll be picking up a bells 2-hearted this wkend (just made a clone and want to do a comparison). I'll give it a good shake to get the yeast into suspension and do that. It only takes a minute (after I get the dilution right, but I suspect I won't have to do that with bottled beer). I'll probably mess around with video again and post some more of that.

I should have been more specific - how about just from the dregs of the bottle, as that is what I'd be trying to culture.

I haven't gotten around to getting stains, so I can't determine viability. That would be a significant concern. But thanks for the reminder. Stains are dirt cheap online, and I think I'll get them for some fun during Christmas holidays.

I'm soooo jealous! I want a microscope! My wife thinks I'm even more of a nerd for asking for one for Christmas.
