Using a P900 with macro attachment as a microscope (10 original photos)

I received a Raynox DCR-250 Macro Attachment for Christmas, and combined with the Nikon P900 at 2000mm equiv. zoom it gives some pretty impressive magnification. My son got a microscope for Christmas and it came with some sample slides, so I thought I'd see how much detail I could resolve on the slides using the macro attachment...
