From time to time I try different video cameras to find the best microscope / camera combination. All the cameras show some aberrations at low lighting levels. Can't quite make my mind up whether this is on the IR filter which they all have or some aspect of the sensor which only shows at low light levels.
This experiment was with a Siemens camera which is good quality but unfortunately shows a lot of aberrations. I have tried different high magnifications object lenses and that makes no difference.
This time I managed to obtain some closer views of the life in a bit of algae taken from the pond waterfall:
Once again I haven't managed to identify the various forms of life.
