The large 75lb rock with the corky finger behind it and the duncans on it are the focal point. The mushroom rock is to the left and behind it. The balanced plate on the 75#er has four points. The Duncans, and to of the plate rock points line up exactly on the focal line, which is 31 inches or so, I forget. It's an 8' tank so whatever than works out to. I walked Sophia out there when I was done and covered her eyes. I got her far enough away where she could easily see the whole tank. I centered her in relation to the tank and told her that when I uncovered her eyes I wated her to show me the first thing she looked at. It was the Duncans. I was elated.![]()
