Re: New to the hobby but have experience with microscopy

Re: confused about retarders

Thanks to you all.
So many articles and posts that mention retarders do not have a clear explanation for beginners. I truly appreciate your quick and simple responses.

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.
Thanks,\

Re: Heat set: why and when?

Thanks for your replies.
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.

Heat set: why and when?

I've seen many references to heating slides, but no info on why to do this or when to do this. I need to be educated.

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...

In Oliver's video 028 on Vitamin C under polarization, he shows heat drying the slide. On the Facebook Amateur Microscopy group, I see references to heat drying. I know how, but I don't know when. I experiment by mixing various substances/chemicals but I don't know when heat drying is appropriate. G...

Re: AmScope

My first microscope was an Amscope M149 that came bundled with an eyepiece camera. My one complaint is that the LED began to flicker which was annoying. My other complaint is not about the microscope: I wanted a mechanical stage. I went through 3 of them that failed because it is possible to run the...

OK, I'm a beginner so I need some education on this.
What is the purpose of the needle?
Where is the needle to be pulled? Embedded in something?
Why pull the needle? to reuse it?

My Celestron CB2000CF arrived a couple of days ago. I'm happy. It's not high end but has more capability than my AMscope M149 student scope. I think this will suit me for a long time. Did I say that I'm happy?
