I have had some problems with some of the articles Mr. Smith has published on Micscape in the past. I think the current article is the most problematic to date.

Beautifully done sinabro. Thanks for sharing.

Hi Antoni
+1 re: daruosha's post, and don't worry about the delay - we appreciate the time and trouble you have taken to put this together.

Think not what you can't see that the SEM can, but what you can see that you couldn't before you had a light microscope.
Tom W.

Thank you AntoniScott. Very interesting video. Really good to see these things done rather than just reading a description which, no matter how detailed, can never capture the nuances. Looking forward to part 2!
Tom W.

Thanks for the link 75. Very interesting article.
Tom W.

Amazing! That last image really shows the "undulatum" feature very well.
Tom W.

Ahhhh... thank you 75RR. Of course they are bees, now that I look at them more closely They still seem familiar, but I'll just put that down to my continuing decline into senility.
Tom W.

Another beaut 75RR... very nicely done.
Changing the topic slightly, can you tell us about your little fly logo? I have this strong feeling I've seen it before somewhere, possibly in connection with a mathematical problem, but that might just be my geriatric mind wandering!
Tom W.

I'm with Wes. Let's hear the details. Very nice result.
Tom W.

Wonderful image. That 63x just never wears out!

Welcome scottybee from another Ontarian. I'm sure you'll find this a worthwhile place to hang out.

Excellent!!!!!!!!!!!!!!!!!

Depending on your intended use, if you decide to try silicone sealant, you should be careful about which type you use. Most sealants intended for household use, e.g. bathtub sealant etc., are compounded with antifungals, which can be harmful to living organisms. There are sealants made without these...

Awesome shots Wes!

Very nicely done Bob. I'll definitely be following you along on this journey.
Tom W.

Caught up with this one rather late. Amazing detail and contrast and beautifully sharp. Very well done - again.
Tom W.

Not a diatomist by any means, but based on many other images I've seen I'd say the COL is definitely an improvement.
Tom W.

Very nice 75RR. I note that your 63x doesn't seem to be wearing out with use - still producing just as good images as ever! The lower image in particular is very good.

+1 on the Ortho-Illuminators - very, very sexy!

Thanks for the update on Part 4 of the series Kurt. I have the other three, but wasn't aware that Tony had released a fourth. As you stated, the books are a terrific source of thoroughly practical ideas and procedures, with attractive and informative illustrations. Tony is a bit of a Vickers M41 fan...

It's apparently available on Amazon Prime video, to rent - $4.99, or buy - $5.99, if that helps anyone.

Hi 75RR I'm beginning to feel guilty about hijacking Radazz's post with this but... I agree that you need to know what the pixel size really is in order to compare it with what is needed. I guess, for me at least, the discussion boils down to the recognition that, in order to figure out what pixel s...

Hi 75RR I think the misunderstanding is because I used an unfortunate term, pixel density, since it implies pixels/mm^2, or some such, whereas I was using it the sense of "number of pixels/sensor". That's because I'm an idiot. :oops: The intent was to get around the issue of different sized sensors ...

The pixel size should be 3 or 4 times smaller that the projected size of the object you are trying to capture. See link and the extract below: https://www.lumenera.com/blog/understanding-resolution-in-digital-microscopy please note that when they say: " largest possible pixel size required to fully...

I've been a little perplexed while following this thread. The idea that resolution depends primarily on pixel size is the idea that's causing me problems. I admit that "primarily" has not been explicitly stated, but seems to be implicit in the arguments. If carried to extremes this would imply that ...

Well... I'm gobsmacked! I couldn't understand what was going on when I read billbilt's posts - thought there must have been some kind of malfunction on the forum, until I read the following posts and realised it was for real. Very, very disappointed - really undermines the forum and leaves a bad tas...

Very unfortunate that this instrument was trashed Piter_. I wish you every success in restoring it to fully working condition.

What mrsonchus said .

I used a 10x objective, 10x eyepiece and 1.6x optovar magnification, both images were cropped from stacked photos. Later I can take some images of a stage micrometer and calculate the number of pixels per graduation to generate a scale bar. Thank you, Wes, for the clarification. No need to generate...
