Here are both the line and the dot diagram for the Brown-Nassau device. I created a version by printing one on paper and the other one on overhead transparency. The principle seems to work quite nicely, though it may be some work to get the kind of accuracy that would be needed in navigation. But for sight planning or star identification even a simple device will be useful.
