I have not taken a single micrograph this year. First i have to organise the images I made last year. A lot of work. I had some trouble with uneven coloured lighting because of a damaged element in my microscope. Before I make new images I have to make sure my set up is workign better so i have as little post processing to do as possible. And start with a clean sensor. Here is a series of images of microbes that form a cluster. With algae you can use their phototaxis to concentrate them.
