That looks a little small for a 100x objective. Was that 100x total magnification ?
Any idea of the size of the Desmid ?
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

Very good oblique illumination giving a distinct 3-D effect for the Closterium. Would you kindly explain what you mean by "oblique dark field eye piece projection"?

Thank you. And what about "10x eyepiece projection"?

It's how I take photos with my Canon (60D); thru the eyepiece to the camera sensor. JimT
