Re: My Latest Microscope

Still looking through our unidentified fossils. Last week we acquired a collection of fossils from our neighbor. He and his wife collected quite a number of fossils from the Normandy coast over a number of years. While searching through https://www.paleontica.org/ for the previous item I came across...

Re: My Latest Microscope

Just been trolling through our fossil collection of some of the smaller items (kept in a jar) and trying to identify various items. Success on one of them. I have wondered for a long time if this was a tooth of some kind of fish. Images taken from Optica SFX90 with mobile phone camera and trimmed wi...

Re: Advice on upgrading a stereo microscope

They claim to be manufacturers !! but I am not totally convinced. I do have one of their scopes and I am very pleased with it (still). Here is the supplier that I bought my scope from when I was at a mineral show in Clausthal-Zellerfeld (where they are based):- https://www.winlab.de/schule/mikroskop...

Re: Mushrooms! Swords! Spears!

You will need a 100x object lens to see the spores and get measurements which you will need for identification.

Re: Mushrooms! Swords! Spears!

Sounds to me that you need two scopes, a stereo scope for the artifacts and a trinocular (so you can also take photos) microscope for the mushrooms.

Re: Objective FN versus Ocular FN - Compound Microscope

Hi John.
I guess it is more of a personal preference and on what one expects to see, as I find the 22mm images to have more detail especially on the un-enhanced images. Still an interesting question and experiment. (I looked at the full set on GP)

Re: Video Editing Software

Gave Shotcut a try and for what I want it is perfect with lots of file formats supported. I have old version of Adobe Premiere Pro which also does the job but does not support the newer versions of movie files.

Many thanks for the heads up.

Hi 75rr Perhaps you are correct maybe we shouldn't kill all these microbes there would be a lot less humans on the planet and therefore more non humans, which would of course still die due to those pesky microbes which infect them.

Re: thinking out loud here - moral thoughts

We all kill and absorb thousands of microbiological organisms weekly if not daily in our bodies, why worry about a few in a microscope petri-dish? These microorganisms would not care (even if they had the ability to care) if they killed you in the process of their invasion of your corpus. Morals are...

More from our garden. This plant is on the black list for invasive species in Germany, maybe I should pull it out, only its so pretty (I think I probably have the wrong identification ;) )

Re: Home made (Very Basic) Microtome

HI Bob.
Posts about plant sections seem to get very high numbers of 'views', but I don't think there are many people actually making plant sections. There are not many posts on plants, most seem to be about pond life.
