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.

Really not much to say more then that it does what it say it does. Makes your viewing angle a bit more comfortable and corrects the picture. Well made, easy to use and looks nice. If that is what you whant, look no further
I used this in combination with the MK105 for terrestrial viewing and the images were fantastic! The BAK7 prism glass and baffling provide clear and crisp daytime views with natural color. Definitely an excellent value. The 45-degree angle and upright views are just what you need for daytime viewing. My preference is for a 90-degree diagonal at night so I have not used it for viewing stars.
