Re: Shell picking from Red Sea sand

This is an exceedingly interesting thread, well done sir, thanks for posting! :geek:

The "zebra stripe" foram in 21 is spectacular. The last two are mysteries to me also - I have found similar objects in beach sand from various locations in the USA.

Re: Bobs traveling microscopy kit (plancton)

A question, if I may: How many net strokes/sweeps are required to collect a meaningful sample ? I mean, when one stands by the water side and just sweeps water with the net that is attached to the telescopic handle. Obviously, the crop depends on the concentration of game in the sea water, yet perh...

Re: Bobs traveling microscopy kit (plancton)

Definitely a great article on designing plankton nets (thanks MichaelG.), but I gotta say this sorta stuff worries me a little: "While many decisions must be made to design a net in full, three key parameters are the most consequential and need to be decided first: mesh size, mouth diameter, and ove...

Re: Bobs traveling microscopy kit (plancton)

Great post! I carry a travel kit consisting of tow plankton net, handle plankton net, and scoop collector as gathering devices. Don't have a picture of my tow net, but it's similar to the handle net below, and made with a lampshade upper hoop for a frame. I also have a bag full of tools, sample cont...

Re: Foraminifera

Very Cool -- is that a living foram I see?? Foraminiferae have their similarities to the diatoms: both create tiny "seashells", and most illustrations show only the shell and rather make a mystery of the organisms that live(d) in them. Forams are amoeboid creatures, but make shells that really bring...

Re: Nikon S-Ke with lots of accessories - A humbling experience, help needed

Yes, a lovely haul indeed! I get a feeling that whatever you paid for it was probably okay, as you seem to have ended up with a very complete and original array of kit in very nice condition, and for us it's a rare and wonderful thing to see. It's exceedingly nice that it appears to have found an ex...

Re: Greetings

Pretty broad question, there. The ideal first microscope for me was a pretty bad toy given to me by Santa in 1970 when I was 10 years old, because it ignited a lifelong love affair with microscopy even if it was largely useless. That may not help you, so try this: for many folks coming into the hobb...

That's a Diaphot TMD in the "Nikon U" link, as opposed to a Diaphot 200 or Diaphot 300. I know next to nothing about the latter two, but have owned a TMD since last summer, mine equipped for phase contrast and DIC. From the very first I have had zero interest in using any of my many other microscope...

Re: Product review: small aftermarket stage for stereo microscopes

I bought one similar to this a couple years ago: https://tinyurl.com/yye2wbwl . While it has its uses, it's largely unsuited to use with microscopes because of its rather generous bulk and heft, often unusable due its height (around 2") alone. It shines as a macro photography studio stage, however, ...
