8.Tips：But all Prism Diagonal – no matter how good they are – suffer from one design feature: There is a line going through the center of the image, where both sides of the prism surfaces come together. This may cause reflections or spikes. To some extent, this will always happen when a bright object like a star is viewed in front of a dark background like the night sky. This should be obvious only with very bright stars or planets.
