Re: Is There A Hydra Doctor In The House?

Here are a couple others that appear more diseased or injured. Very strange, have never seen this kind of thing before.

Is There A Hydra Doctor In The House?

Took a New Years Day peek into a micro aquarium and got a bit of a surprise: growths on several Hydras like I've never seen before. I understand Hydra can reproduce sexually, as well as by budding, whereas some individuals develop testes, others ovaries, and still others ... both. Anyway, the testes...

Re: A desmid (BF, oblique, COL, DIC, and pol illumination).

Wonderful series! I always like seeing and comparing different lighting schemes. What is your scope again? Also like to hear how you get oblique, as your approach really brings out the detail!

Re: Objective quality opinions

I have a Nikon E600, definitely recent infinity optics. The threaded portion of objectives measure just over 25.03mm according to a Harbor Freight digital caliper and my clumsy use of it. If desired, I can test whether objectives from my Olympus BX45 will interchange. http://i70.photobucket.com/albu...

AO Spencer Model 28LF, Yet Another Stereo

No, I'm not obsessed with this family of stereoscopic microscopes. At least, I don't think I am. But dang it, the swing arm had my curiosity piqued so I made a ridiculous offer and the seller accepted so now I have three very similar old stereos. But it's no hardship, each has cost just a little ove...

Re: POL Fun With Citric Acid

Yes, "doing acid" is lots of fun! :lol: It had been a while since I did any of this, and Rod reminded me of it with a recent post. I have spent many an enjoyable hour just tripping on kaleidoscopic crystals under crossed polarizers, almost like the video games of microscopy. 8-)

POL Fun With Citric Acid

Nuttin special for sure, but had a bit of fun making crystals while de-cluttering, straightening up, and reorganizing the lab today. One thing's a given: with crystals you can never know what you're gonna come up with. The one run of crystallization running such a straight path was pretty amusing to...
