hello
a posted article recommends sand as a useful object of study:
If you can obtain a sample of some of the famous sands containing fossils, they are particularly interesting. The image left shows a famous sand from Dog's Bay, Connemara in Ireland.
do you know of a resource for same...?
thank you...

Try search "foraminifera" and " microfossil" on eBay. Kdfossils is the seller.
I have this sand sample and it has some interesting micro shells too:

Most of that Sandman's Hawaii sand samples have some micro shells. He combines shipping, though his sample may have more sand than micro shells - Sandman does not examine his sand up close but kdfossils does (kdfossils may have more micro shells).
But Kdfossils' sample amount is very tiny.

belated thank you, zz...
I did locate the eBay vendor (Kieran), and they will be sending a variety of samples...

^ You are welcome.
Please do share photos of your micro fossils, when they arrive. I may be interested in getting some as well.

speaking of photos, is there a way of removing one of the American Optical 150 eyepieces and, via an adapter, attaching a Nikon DSLR?
Best,
Dean

You can keep eyepiece there, add this adapter to connect your camera and a 50-60mm full frame equivalent lens

not sure about the lens referred to here...a Nikkor lens? or, one suited solely to this rig...

No.
If you have Nikon DX sensor (which is APSC crop factor 1.5), then you should use a Nikon prime lens with (a single, not zoom) focal length of 50-60 / 1.5 = 33 -40 mm.
Between the frontal thread of your Nikon lens and that adapter, you also need some lens step down or step up adapter rings.
That adapter has 42mm thread.

Hello, stone white...try on EBay searching for a : relay-lens camera adapter. My ancient Nikon FM, and more recent (still an elder style camera) Canon rebel-xt,dslr cameras adapt to my 160 TL microscopes via these: relay lens camera adapters.
Charles Krebs, a gifted and public shareing microscopist and image capture expert (Nikon Small World award winner perhaps just a small part of Charlie Kreb's activities)...please 'google' : Charles Krebs Microworld...or something like that for excellent advise on a variety of ways to mesh your dslr-camera to microscopes.
