Re: Pollen. There's lots of it about.

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 ;) )

I also have a Bresser Infinity. I used a spare eyepiece and the adapter from my Bresser USB camera to connect my canon DSLR 4000d camera.

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.

My Latest Microscope

Just acquired a new stereo microscope at a bargain price. Optika SFX 91 from a mineral borse (show) in Clausthal-Zellerfeld where we were attending a week long course on minerals (our third in the last two years). Half price made it an unmissable buy.

Re: Hello from Connecticut

Hi Mickey. Yes my camera is setup. I used a spare eyepiece that I had to connect all the bits together. The view through the camera is about 5% smaller than through the eyepiece but I can live with that. See here for a comparison, the two images are 180 degrees apart:- http://www.microbehunter.com/m...

Out in the forest on Sunday and found this. It's amazing how many plants were used for medical purposes in the past.

Re: No idea I

In order for people to help to need to state the basics: Where you found the sample and what the magnification is of the sample, at least. Without those two most basic pieces of information there is no chance of any help. They could be pollen grains, they could be spores, did you stain them or is th...

Re: Pollen. There's lots of it about.

Hi David_b Thanks for the suggestion of ragweed. It was (and is) the correct flowering time for them, however from what I could find on the internet the Ragweed pollen is only 15-25 um in diameter which would rule out this enormous grain. If I am wrong on the size please let me know. I have to admit...

Re: Pollen. There's lots of it about.

Hi John,
That's what I thought and the reason I decided to post it. I checked it out on PalDat and it looks exactly the same. The image under the scope was much clearer unfortunately the stack didn't turn out as good, I think I rushed it a bit. (was so excited Ha :D )

Reminded me of a pineapple.

Sweet Basil growing wild in the garden must have seeded itself from last year (we never planted it).

Pollen is an unusual shape:-

What do you expect to see from an aquarium with a 100x lens that can't be observed under a 60x? you wouldn't need to use oil at all.

Re: What was your First Microscope?

Good on you Dave, and we wish you many more years of fascinating microscopy. The average weekly wage in the UK as of June 2019 before tax is 505 pounds, so you would have 1515 pound to spend on a microscope today. Less tax of course, not a bad scope. :D
