Try placing the slide on a cold plate to slow things down. We used to use that trick for insect macrophotography.
Shssh don't tell anyone how we cheated all those years. Sometimes a little spray can of volatiles works to cool and slow things.

My report: I e-ordered some well slides and coverslips from: <http://www.microscopeworld.com/> I inserted a 4GB SDHC card into the LCD/Camera head of the scope. That worked, and I'm using that mechanism for file transfer. The stills are JPEGs, the videos are 3gp (whatever that is, but miraculously both my linux boxes could display it, so kudos to Celestron for choosing that format). I went down to a pond in Tilden Park and collected some samples. Here are my first attempts at capturing images: <http://www.panix.com/~bks/Pix/Micro/> The two minute video is pretty cool for a first go. I am definitely a microscope tyro. Some of the little guys are zipping around too fast to follow, and most are too small to make out much detail. If you stick with it till the end you'll see another large critter go zooming by. The still pictures of pond scum thingees are not great but for larger objects, like the prepared section of a stem of a plant, they're pretty good. The verniers on the stage are pretty good for such an inexpensive instrument. It sure beats using your fingers to move the slide around. More in the future. Mostly this makes me want a better setup. But as that would be between 10x and 100x more expensive, I'll wait. ===end=== ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
