Many microscopes these days are capable of "live imaging". Viable cells can be placed under the microscope, the lens magnifies the image, and the magnified image can be sent to a highly sensitive digital camera. You would probably need to use some stain, something that binds DNA, to make the chromosomes easily visible within the tissue.

what is serial dilution and spread plate technique
Chromosomes were first observed in plant cells by Swiss botanist Karl Wilhelm von N?geli in 1842, and independently in Ascaris worms by Belgian scientist Edouard Van Beneden (1846-1910). The use of basophilic aniline dyes was a fundamentally new technique for effectively staining the chromatin material in the nucleus. Their behavior in animal (salamander) cells was later described in detail by German anatomist Walther Flemming, the discoverer of mitosis, in 1882. The name was invented later by another German anatomist, Heinrich von Waldeyer
Williston et.al and waksman et.al discovered the crowdwed plate technique.
Chromosomes are easiest to see when they are condensed(coiled and supercoiled, so that they become short and fat).They are at their most condensed from late prophase through to early telophase, in either mitosis or meiosis.Their visibility also depends on suitable microscopic technique, including the use of an appropriate stain, such as acetocarmine.

Rubber band ligation is a technique that works well with internal hemorrhoids that protrude outward with bowel movements.
It used to distinguish autosomal and sexual chromosomes of a species.
