Re: Oblique filter suggestions
I can sometimes achieve obliqued-ness by setting the phase contrast condenser between stops. This is photo is 40x and the condenser set between 0 and 10 (Olympus BH2 BHTU setting). The same setting using the 20x objective gets me to dark field. https://www.smugmug.com/app/organize/Micro-unknown/Misc...

camera settings for LED lighting
I have been using an Olympus BH2- BHTU and a Canon EOS 5D Mark II for several years. Using tungsten lighting I set the camera to ISO 640, shutter speed 1/80 and white balance tungsten. The camera is tethered to a Mac and I focus and tweak the setting based on what I see on the computer screen. All w...

Re: van Egmond masks
I tried follow the directions, but I seem to be mechanically and artistically incompetent. Fortunately I found a kit for sale on eBay for $50 which I have been pretty happy with. The seller makes the set for a variety of microscopes. This isn't an ad- I don't know the seller. https://www.ebay.com/it...

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: mystery organism in pain
Sorry- I erred a few times trying to post this, most importantly by putting it in the wrong group. I cannot identify the organism and hope that someone else can.
I lived in Bremen for a few months. You're lucky.

If we all maintained a .01% level of Glenlivet (18year) we would not be concerned about this. I strongly believe this because a member recommended it.

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.
