Re: Coverglass Clamp
Love this idea, always a problem with as you say thicker mounts.
Just ordered a pack of 20 from you know where, <£7 delivered to the U.K.....
Thanks for the tip.
Great for permanent hand-section mounts not to mention smaller whole-mounts.
Ordered these, they look identical to yours,

Simply fascinating, and a great image - I suspected they were squashed-down but no problem there! Nice level of detail - the number of spicules may be of taxonomic value too, as it is said to be in that excellent PDF of the new species discovered. May I ask what set-up you're using?

Re: Electronic Front-Curtain Shutter
The article reminds me of a question I have on shutter shock: To what extent will the in-body image stabilization offered in some of the newer cameras help with this? Since in-body image stabilization works by moving the sensor to compensate for camera shake, unless I'm missing something, it seems ...

Hmmm, the plot thickens...... They have a look also of some type of spore-cases, but their apparently ordered orientation 'along' the legs in particular suggests otherwise? More detail/research is needed! Great images and subject.

So, do you mean when you say "left it in there" that you left it in the GALA 40 then water-rinsed? What did you mount it in, just water? Did you find it with the dropper when it was in a water-bath, then drop the specimen (in a water-bath drop) onto the slide then seal? What happened with the G-40? ...

It really is very handy, but I certainly like metal parts!

I don't use a hand microtome for hand-sectioning either - they're far too laborious in use I find. I simply hold the part in my fingers and run the blade parallel to my finger-nail, with a tiny change of angle (from the very-nearly-vertical) another section may be cut. With a sharp blade this simple...
