Re: thinking out loud here - moral thoughts

Over the past few days I have watched a coleps ingest a small cell, fungi attack a rotifer (I think), and an amoeba engulf a diatom. This seems to be what nature is about. While I applaud your concern for the lives swimming in the samples we collect I try not to be too obsessive about it.

Re: Darkfield using Olympus BH2/BHS

I just purchased this everything (oblique, darkfield, polarizing, Rheinberg) kit specifically for BH2's. I've only been playing with it for a few days, but I'd delighted with it. https://www.ebay.com/itm/Olympus-microscope-condenser-darkfield-polarizing-Rheinberg-oblique-insert-set/264323855175?ssPa...

Re: First bacterial culture

Before I retired I was an epidemiologist at the infectious disease bureau of the NYC Department of Health, which is why I am concerned. Nothing could make me play with bacteria without strict sterilization protocols. How do you handle the less photogenic aspects of bacteria?

Re: What kinds of bench furniture and storage do you have for your hobby?

We are in the process of renovating a cellar and I've carved out an 8' x 12' space for microscopy work. This won't be reality for another few months so I haven't done much real planning other than a very sturdy, washable work surface with lots and lots of electrical outlets. I'd be interested in any...

Re: NY Times Video Report on Pond Micro Life

I sample the waters of NYC, too- mostly in Prospect Park, Brooklyn. I noticed less life near the shore in warm weather than cold weather. Algae (schmutz, as it's called in NYC) disappeared, leaving only cement and dirt near the shore. People fishing have not noticed any change. Does pond life migrat...

Some sort of bug caught in a spider web. Judging from the black threads, s/he is being sewn in. Can anyone identify the bug? Thanks ahead of time. 10x

Re: red bug- what is it?

Lesson learned- I will measure from now on.

The tick/mite was not visible to the naked eye but was huge compared to anything else I have seen so far. Mites live everywhere, but ticks (I think) are rare in cities.

Again, thanks for your help.

red bug- what is it?

This photo is a still from a movie. The top one is fighting to get out of the web that already killed bottom one. The sample was gathered from moss growing on a tree. It's not great art, but I would love some help identifying them.

Thanks ahead of time.

Re: Book on Microscopes

Another great book- Practical Digital Photomicrography by Brian Matsumoto. It's mainly about how best to use the equipment- the lens, digital cameras and how to mount them to the microscope, improving the images, and buying a microscope. It's an excellent book for the informed beginner.

Re: camera -> microscope connection

Just a few things to keep in mind with a BH-2. 1) If you're using Olympus objectives, and not their eyepiece or NFK projection lens, you'll get uncorrected (or improperly corrected) images, with significant lateral chromatic aberration. This will limit your results you can achieve, once you work th...

I would be happy with an NFK 2.5, but at $140 on ebay, they're not totally cheap. I realize that I would probably need to buy a canon body to pull this off. V1s and J1s are hard to find and as expensive as the used rebels I'm contemplating. One question that occurred to me- will this solution make t...

Re: camera -> microscope connection

so only an NFK should be used here. I was unclear- I do have a 3.3 NFK which I have read that should be changed to a 2.5. From what I have read, for the projection method I have to drop an eyepiece adapter over that, connect it to a photomicro adapter L. The adapter L is constructed to fit into an ...
