Draparnaldia

I am sampling local streams for invertebrates and algae, and came across this alga 10 days ago. I only found one rock with obvious growth in the pool I was in, and it had what I took to be two different types - the filamentous one is Draparnaldia, and the spherical one I thought was probably some sp...

Re: Microscope storage/portability options

I made a box for my Wild M3B which I am reasonably comfortable using for transport in the car - box is made from 1/4" hardwood plywood on a hardwood frame, hardware is from Penn-Elcom fastened with 3/16" pop rivets. The base has a full 1" layer of foam with a second layer cut out to capture the base...

Re: Why is photo sharpening necessary

I believe I could get better than this by fine tuning the photo port tube length I can well understand how the wrong C-mount adapter would result in poor images - every camera lens-system has a flange focal length which is the distance from the mounting flange of the lens on the camera to the plane...

Why is photo sharpening necessary

Almost all my images benefit from sharpening - I'm using GIMP photo editor. The two images below are a rather extreme example, but the blurry image is much improved by sharpening, without any apparent (to me) degradation. Subject in Hydropsychidae larva. The details derived by the sharpening process...

John - I had started out with the camera the other way, and I don't remember if the image was upside down, but I didn't like the menus upside-down, so that is why I switched.

The D10NLC OD is 38mm = 1-1/2", so that connects to the 1-1/2" OD drain with a slip-over rubber tube. Total cost $6.49. It is closely ...

It appears that Motic reworked the photo bridge but did not update all their brochures.
Thank you, John. Same part number 1500.3 - different part. Go figure. I will work up something with M42 spacers and post pictures of outcome. May take a while.

It would end up being similar to the tube that comes standard with the Wild phototube - this is my M7A with Wild tube, without camera.

Re: Wild M3B with Motic 1500.3 photo-bridge

Just to be clear, you want to direct project onto a c-mount camera? I am using a mirrorless camera without lens - Olympus Pen E-PL7 - with a C-mount to Olympus adapter connected to a lens-less D10NLC 38mm ISO to C-mount. So, no, not a c-mount camera per-se. D10NLC C-mount to 38mm port adapter.jpg

To get an accurate alignment it is best to use 2 goniometers.
White foam on top of the upper goniometer.
Tony - I of course had to find out what a goniometer is - what to me is similar to a carpenter's bevel square. Can you please post a picture of your setup with the foam attached to the upper?
