Wrap Around Eyepiece Cameras

This type of camera is unusual but can be extremely useful.  The camera fits over an existing eyepiece on your microscope (or telescope incidentally).  This means that you benefit from the quality of the lenses in your eyepiece rather than hoping that the c-mount adapter is of equal quality to your eyepiece.  The other advantage is that this device can easily be attached to a multitude of microscopes without any intrusion or altering of the optics.
