Hi there,
I saw a website where you could key in the magnification of your eyepiece and its numerical AFOV, and it would show you the FOV as a circle on a certain piece of map. This would help me to visualise the real FOV of the eyepieces before I buy it. But I forgot which website it was. An example of the FOV diagram output (or similar) is shown below. Please help me to identify it.
