Re: Fossiliferous chalcedony

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...

Re: Diversity in one sample from aquarium

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.

Re: Diversity in one sample from 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...

Re: What's the coolest subject for stereo?

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.

Thanks, all! The idea of vibration from the fan gets my attention, but since nobody mentioned it other than in passing I assume it really doesn't amount to much of a concern? Do all the 150W lamphouses have a fan, or are some passively cooled similar to 100W microscope lamphouses? And what about tho...

I recently came across this very pretty bit of greenery while perusing water from a local pond sample, and thought for sure it must be some Desmid I haven't seen before. But a more experienced friend suggests it's the alga Coelastrum. I can see where he gets his ID, but it still strikes me as a Desm...
