Re: Crazy Crystals

Your photos are wonderful. Some of us amateurs enjoy working with crystals, too. I'm a member of the

Crystal Art Photomicrography group on FaceBook. Some members post remarkable pictures. It's fun to see what will show up.

Re: Displaying my images on YouTube

Thanks for all your comments. As to audio, when I come upon a video with only music, I always mute it. In searching for music for other videos, I've been frustrated looking for free audio clips that I actually like. I purposely make the vids short so I did not think audio necessary, but I agree that...

Displaying my images on YouTube

I have posted some of my favorite images on a YouTube channel. They are all short with no narration or annoying music. I will appreciate your comments and/or questions. Images are on screen for 5 – 7 seconds. Too long? Too short? Improvements? Mary's Microscope https://youtube.com/channel/UC-BSLjwNL...

Rotating Retarder

My new trick: rotating a retarder to get a short movie. This one is Vitamin C mixed with an energy drink under polarized light.

confused about retarders

If I have a retarder, where do I put it?
Please no technical notes about optics or wave plates. I'm just trying to understand how to use a retarder.

Unlike most of you, I am currently enthralled with chemicals rather than microbes. Techniques may be different. The images may be blah, interesting, beautiful, spectacular, or just weird.

Re: Darkfield and Reinberg filters

I just now ordered from Esslinger: 8 watch glasses: 32mm, 1mm thick @$1.25 each. Shipping via USPS first class $3.63
The website says that they may be back ordered on some items, but does not specify which ones. At that price I can wait a while if necessary.

As a rank beginner, it has not been easy to learn about condensers. My student scope did not have one. My big excitement about having a condenser on my new scope was because it has a filter holder. I wanted to learn about how to use it. My internet searches brought up all kinds of technical informat...

Why pull the needle? to reuse it?
