It is my understanding that a Galilean telescope has a smaller field of view (FOV) than a Keplerian. Doing some "pencil" ray tracing on a sheet of paper I don't seem to get this result. Can anyone suggest a source that works the math for the FOV of both types?(adsbygoogle = window.adsbygoogle || []).push({});

thanks

Fritz
