I'm working with a NOVA reverse objective (inverted) microscope with a camera hookup. I don't know anything about microscopy, other than what they teach you in high school...and I never showed up to for that class.
Furthermore, the camera hookup was intended to be used with the included 35mm camera, and being as unpatient as I am, I just kind of hold my Nikon digital over the opening, let it focus as best as it can, and snap pictures.

That's the microscope, of course. It's a pretty nice microscope...but it didn't come with a manual.

These are the spores at 250x normal size, approximately.

Spores at 400x.
