Re: Wanted: Nikon CF plan apo 60x
Thanks for the kind and helpful responses. I am excited to hear several glowing recommendations of the objective.
Tonight I will take some pictures of the process of making slides of my fossil material, and post some sample images.

Re: Wanted: Nikon CF plan apo 60x
Thanks for the heads up. I think I might bight the bullet and go for the objective at deal corner. I've got a 60x plan achro that I use quite a bit, but since I am making color micrographs for publication, I'm sure the plan apo will give me a bit better color rendering. The plant and fungal fossils ...

Wanted: Nikon CF plan apo 60x
Hello,
I'm looking for a Nikon CF plan apo 60x dry objective. The newer CFN 60x plan apo oil objectives are much more common, but I'd like to stick with a dry objective for the fossil materialI work with. Please contact me if you know where I can find one.
Thanks!

Looking for a B&L Stereozoom stand
Hi,
I'm looking for a stand for a stereozoom head I just bought. Given how common these microscopes are, I'm surprised how few stands are for sale on Ebay.
Anybody have one they don't need?
I'm looking to use it with a Stereozoom 7 if the model matters.
Thanks!

Re: Moss Hand Sections
Beautiful leaf preparations! The guide cells (also called deuters) are actually sugar conducting cells in the leaves. Sugar-conducting cells (leptoids) are common in moss leaves, but are only found in the stems of Polytrichaceae. Hydroids and leptoids are found in the seta of many mosses. Hydroids a...

Re: Another Moss Dissection
Also, Mr. Sonchus,
I applaud your desire to make permanent mounts of mosses. Very few mosses have ever been subjected to rigorous anatomical study. Almost certainly if you imbed most moss species in paraffin and make microtome sections, you will be the first person in history to do so.

Re: Another Moss Dissection
Wonderful preparations of both the leaves and capsules! I agree that it is certainly a member of the genus Atrichum, and probably A. undulatum. This moss is a member of the family Polytrichaceae, which possess the most complex anatomy and morphology of any mosses. The lamellae are actually a way to ...

Re: Moss Dissection
It is wonderful to see some mosses in the limelight! The excitement in this thread is palpable. Those archegonia images are beautiful! I find that for mosses a one to one mixture of PVA and pure glycerine makes a fantastic mounting medium which lasts slightly longer than PVA by itself. There is a jo...
