Autumn live microscopy

Let's see what swims in the Autumn rivers, ponds and sea of the Helsinki area. As usual, the event will be online on Zoom where there will be a live stream of the microscope view, but this time with a new Olympus BH2 I just acquired. The event is meant to be informal and relaxed, so feel free to speak during the event or write in the Zoom chat. If you have suggestions for some samples you would like to see with the microscope, let me know by writing a message in the event comments at least a day before, so I can try to collect them.
