Apparent vs real field of view



When looking at specifications for either binoculars or eyepieces for scopes, I often find two data sets for field of view. I think I know that the real FOV means, but what about the apparent one? What does it tell me? E.g. for the SE models, Nikon gives for all three of them an apparent FOV of 6 degrees, whereas only the 8x32 model has a real FOV of 6 degrees.


Robert, I think you misread the specs. All three have 60 degree apparent fields. Divide that number by the magnification to get the real field. Henry

Well, it shows my limits when it comes to optics, I am afraid. However, I still don't understand what is meant by "apparent field". Maybe, you can help me a bit more, Henry. Thanks in advance! Robert
