    You cheap toy will do a lot more than a lot of people think. Concentrating
    and staining the bugs is more important. You can improve the image some by
    cutting down the stray light in the system with a simple stop below the
    stage. Just a round hole that only lets in light that goes directly in the
    objective.

    It won't take good pictures but you can see a lot with them. You don't mind
    taking them out in the field with you either.
