I have an old microscope(probably a toy) 75x-300x-600x. anyway I've been looking though it everyday to see my trics, and I'm not seeing anything like what I see in the pictures on the sites. I've never used a microscope befor, but I was wondering if this particular one too powerful/weak?? Do I look at a piece of the leaf or a pistol, or do I scrape off some of the trics onto the slides (glass)?????
