Microscopy is both hobby and profession for me. Professionally, I am a microscopist and technical director for the Optical Imaging & Vital Microscopy core at the Baylor College of Medicine in Houston, Texas where I teach a wide array of light microscopy techniques to academic researchers. This also enables me to mess around with some of the most advanced light microscopy instruments in the world.
In my spare time, I have built a light microscope that attaches to a digital SLR and allows me to image from 5-20X (objective magnification) in either reflected light and/or fluorescence. This is great for taking high resolution images of all the little critters my daughters catch! Below you will find a few images of this rig.
I have also been known to dabble in landscape and underwater photography, though not nearly as much as I would like. You can see those images here:
