Re: Not happy with my videos
You might have better luck if you can adjust your camera while filming. I have exactly the same set up as you do. My camera (Canon 5D Mark ii) is mounted on the microscope and connected directly to a computer using the free Canon software. The computer screen shows exactly what the camera sees and I...

Some of us are trying to revitalize the New York Microscopical Society. It would be wonderful to have someone with your energy. Sadly, we do not have a web page, but we do have a facebook page.

Re: Tending the jarred pond
Put the jar in indirect lighting, make sure it's open to the air and has enough water that the whole thing doesn't dry out.

Re: Should I Purchase a BH2?
BH2's come is several flavors- my BH2 BHTU is fine but it only gives 6 volts of light- apparently is not enough for DIC. If you think you'll want to do DIC down the line make sure you get a BH2 BHS. The BHS is 12 volts.

Re: Where do you find Stentors?
I'm not sure if this is helpful, at least at the moment. The lake I from which dip supports a huge population of stentors in the winter, not so much at other times. It may be (and this is just a guess) they come closer to the shore where the water is warmer and go back to the center of the pond when...

Death to some, dinner to others
The stentor is dying and probably leaching bacteria which the paramecium are eating.

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...

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.

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.

We are in the process of renovating a cellar and I've carved out an 8' x 12' space for microscopy work.

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...

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.
