Re: Motic SMZ143 with Motic 2x SLR Projection Lens

I'm interested in the Motic projection eyepiece as well and was also wondering how well it would pair with an APS-C sensor. I'm sure others looking into a similar setup would also appreciate those pictures once you have them :D

Re: Bacteria Swarms

Thanks for sharing! It's nice to see some bacteria on here. I understand it's not an easy subject to capture, did you use your 60x or 100x for this?

Safety and Legality of Prepared Pathology Slides

Hi all, I came across this prepared slide kit online, and having never owned any of these before, I wanted to check how safe these are to use, and if there are any known legal concerns when owning these? (Though I assume this is likely country-specific). For example, the prepared slide of Anthrax wo...

They are called "vital" stains and I believe they are much used in fluorescence microscopy. They are not as great as conventional dyes and difficult to differentiate but have the advantage of not immediately killing the subject.
Thank you Bram, I'll have to look into this!

Thank you for the great resource. I'm wondering if it's possible to stain a live specimen without killing it? I think it would be great to observe protists this way, if it is possible at all.

I was fortunate enough to find a rotifer egg just before it hatched and managed to capture the whole thing, hope y'all like the video!

Also, I've been unable to identify the rotifer with any of the keys I have, so if anyone has any ideas that would be much appreciated

Re: Microscope will not focus above 10x

1. I would try to separately focus with the coarse focus knob and fine focus knob to possibly isolate the issue. It is possible to accurately focus (at least visibly) with the coarse knob the 10X and 20X and 40X. Without touching the fine knob. Then slowly rotate the fine focus knob to move the spe...

Re: Microscope will not focus above 10x

This is a finite microscope, right? Not much should be able to go wrong. One thing is the eyepiece position could be out of whack, pushing the higher objectives so far out of parfocal that they can't focus through a cover slip. Are your 4x and 10x perfectly parfocal? Thanks for the suggestion. It's...

If the zoom was set to 45mm, I would guess that 60-70% (may be even more) of the actual field of view (by diameter, not area) was covered by the camera. Based on experience with my setup.
Thanks! For these pictures it was set to 30mm if that helps
