Re: Leica DMIL

Hope this advice isn’t too late microb but I always want an X/Y stage movement on an inverted for smooth travelling across the Petri dish-less sloshing spillage that way also than moving dish by hand-some scopes have the whole stage move X/Y like my Olympus CK-1-other have an add on stage clip of so...

Re: A blast from Nikon's past

Way overpriced-but I bought way overpriced things in the past cos I just wanted it! I’ve studied the Nikon S catalogue soo many times-they had a transmitted DIC addition also though I think it could only do the colourful birefringence variety not the greyscale type-I don’t know a lot about DIC! But ...

Re: Hello from Trinidad

Hi Acuruss-I’d love to see photos of your micro fossils one day in the groups photography section!-sounds like a very cool project-I’ve got some amber with an ant in it-I wonder if microbes get fossilised in certain conditions or substances?
Have fun

Re: My microscope (overkill eyepiece alert!)

Hi-my advice-definitely get a 20x-My favourite used magnification-good balance of sharpness and depth of focus-you could upgrade the 40X to a second hand fluorite objective-they definitely have more ‘bite’ to their sharpness.

Hello peeps-I’ve noticed some objectives have had their thread greased (and hence RMS hole in nose) and others not-should objective threads be greased at all?
