In my youth (the early 1970s), 50 degrees *was* wide field. For a while
there, my best eyepiece was a Ramsden with a 30-degree field.

I would choose an 8-inch with 20-mm-eye-relief eyepieces over a 10-inch with
conventional eyepieces.

And my preferred AFOV is about 60 to 65 degrees. Radians and Pentax XLs for
me!
