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.

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...

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.

Good photo, Bob !

Indeed, very nice!

...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.

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!

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 ...

Charlie, you have outdone yourself!

Really cool.

Would be great to see the steps taken, and the recipe for the mount on the cover slip.

^^^ I second the motion!

I'll add another endorsement for Michel Haak at diatoms.nl. I've been doing business with him for some years now, and he's always been a delight to trade with. His cleaned sample material is indeed wonderful for making your own slides, and his finished slides are likewise first class. The diatoms sh...

Glen, is this specimen shaped like the one I imaged and posted on this thread?

Charles, can you add a word on where you obtain your chemicals? Muriatic acid I know to be available in home improvement/hardware stores, but any comment regarding concentration? I seem to remember there being some discussion of having to be careful to buy the 'strong stuff'. And where do you get su...

Your images are nothing short of thrilling, and I'm always all over your posts! Please keep 'em coming!

Yes, a most excellent image of a diatom I personally know to be the very devil to get a good image of. Once again 75RR proves to be the wizard of the 63x/1.4 planapo, an objective lens I personally know to be the very devil to get good images through. :ugeek: <--- Here you go, the Uber Geek Award is...

I will document from start to finish, processing these from raw diatomite to the finished type slide.

Most excellent! I am already very much looking forward to each and every installment!

Wow -- just wonderful! Don't see living forams any too often...

Charles, just want to say thanks as always for posting your finds. That's a really cool scope I never would have known a thing about otherwise.

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?

Having location makes all the difference in the world to me. It always annoys me when it is not given as it amounts to missing information, and I'm always much more interested and appreciative when it is.

Nice detail in that image, as we have come to expect from you and your deadly 63/1.4. Mesmerizing, even. Isn't it grand how those wee weird creatures craft such wonderful microscopic structures?

Truly spectacular photos, Håkan.

Inselberg is such a delightful word, too.

Indeed!

Wonderful post, thank you Håkan. Please accept this Uber Geek Award all the way from Texas --->

Perhaps someone who understands what this image is showing could give a description for those who do not? This is a branch of study which many are unfamiliar with, including yours truly. It's pretty, but uninteresting because I don't know what I'm looking at other than 'Fossiliferous chalcedony', wh...

Oh I don't know, I find it perfectly whelming, myself ... how 'bout you, Glen?

Seriously, and as I said, the variety of life forms you present makes the whole thing impressive, which makes it a grand little pond aquarium.

I second the motion for pix of the aquarium! I find your assortment of wee beasties impressive, and can only assume you're keeping a splendidly healthy little ecosystem there, whether through a specific set of skills or just plain good luck. I do know perfectly well that some samples seem to stay cl...

Oh my. Now that was one seriously beautiful bit of photomicography (videomicography?)!

^^^ This guy clearly has a point.

WOW!!

I get troublesome vibrations from someone walking across the house (soon to be rectified)

No violence, now...

Thanks again, everybody!

Three answers immediately spring up in my mind: Using the stereo to examine pond life samples in their containers, before making slides and taking them to the big scope, gives wonderful perspective on the organisms you simply don't get any other way. Using the stereo to monitor knife sharpening prog...

Yes, very nice indeed - I believe that's the first time I've ever seen florescence images given over to gray scale.

It's also very nice to see you back at it, I've been missing your postings!
