Copper dendrites form during electro-deposition
The distance between the Cu electrodes was about cm and voltage was 2.4 V, but you can do this experiment with 5-10 cm distance which can be already filmed with an ordinary camera. Of course you would need higher voltage, probably 10-20 V DC. You can experiment with CuCl2 solution concentration to get wider structures. Any microscope is suitable with magnification range from 1x to 5x. You can even use a DSLR with a macro lens.
