Re: New Diatom Project

Thanks Charles. And what kind of heat are you using, butane torch or alcohol lamp or what? The micro torch runs awful hot, but that can be mitigated with distance. I have trouble getting consistent flame action with alcohol lamps.

Re: New Diatom Project

Charles, I finally made it home today, and wonder if you can point me to your needle-pulling discussions, and/or anything else on the subject you think worthy of attention? I intend to revisit the needle-puller apparatus that Keith has been working on, as it especially piques my interest. But I have...

Re: New Diatom Project

I'm admiring how fine your needle is!

I know you've discussed needle-pulling, but I have been unable to do anything in the lab because I haven't seen my home since February. But when I do get back, that's one thing I want to tackle right off: improving on my needles.

Re: Incoming! Olympus BH-2 ...and a question please

...there is far more scattered light in a telescope...
It's the same thing, really, whereas telescopes suffer from "scattered light" because they're seldom properly baffled, particularly at the focuser. Yes, OT, but I had to say it.

Re: Campylodiscus (hibernicus?)

That's one of the nicest presentations I've seen yet for describing the very confounding shape of these things.

Wonder if you might add a comment or two on how you manipulated the specimen to get your various perspectives? Again, nicely done!

Re: Inverted microscopes

Are inverted scopes better for observing pond microorganisms? No such thing as a 'better' scope for observing anything ... it depends on what kind of observing you have in mind. For example, I'd argue that the best scope for observing pond critters when first looking into a sample container is the ...

His cleaned sample material is indeed wonderful for making your own slides, and his finished slides are likewise first class. The diatoms sh...

Lovely diatoms, and images of them. Well done, sir.
Always seem to be plenty of diatoms to be found when one picks some up with tweezers and taps lightly on a slide.

Try tapping harder and see if you get even better results? 8-)
