Re: Hi from Morecambe

Just to add a welcome from someone else here in the UK. White Rose, not Red Rose.... Many years ago, there used to be an amazing 'shop' in Morecambe, near the front somewhere, that was rammed with scientific stuff, including many microscopes. Long since gone, but the image came back to me as I read ...

Re: Nikon bulb 77910

I have a Nikon model S microscope with a differential interference contrast attachment. The lamp has blown. I think it is a 77910. I haven’t been able to fine a replacement yet in the uk. I think I have 3 options. 1) find a replacement from somewhere outside the uk 2) find a BA15D bulb without the ...

Re: Naphrax vs Pleurax vs Cameras vs Me!

Great thread! Very inspiring to this one who is new to diatom arts :) Does anyone happen to know if there is a supplier anywhere for Pleurax? I hope to try hobby46's recipe for homemade mountant, but as a backup I thought I might try Pleurax as well, as it seems to be the least toxic to use of the ...

What is the compromise of using this instead of the one for 0.17 cover slip? My intention is using it to capture crystal on slide, watch some dyed slide or slide without cover...

Not the same species, but similar.

Taken with a x10, which has greater depth of field.

Cropped, to be comparable.

Zeiss Ultraphot II, instruction booklet

In searching through a large pile of literature, I found an original copy of the (A5-ish) 92 page instruction booklet for the Zeiss (West) Ultraphot II, dated 1967.

This is free to a good home, for just the cost of postage (from UK) but is in German.

Re: Dovetail on the bottom of a BH2 1.25 condenser. 

It might be worth mentioning that the Nikon and Olympus dovetails are very similar, with the Nikon being slightly smaller. Hence, a Nikon condenser will fit an Olympus stand, but not vice-versa. There are a *lot* of similarities between say the BH2 and Optiphot (and others) stands of these two maker...
