Even if the number of millimeters is the same, the larger the number called the apparent field of view, the wider the field of view, which is advantageous.Is the field of view flat? A good lens is one that allows you to see a flat field of vision even when you shift it from the center to the periphery, as if you were shifting it on a plane.Is there little distortion? It's a good lens if the star image in the periphery looks like a dot.Isn't it colored? It is a good lens if the star image is colored and cannot be seen due to chromatic aberration. Does it have a long eye relief? It is easier to observe and is advantageous if the position where you can see the entire field of view is far from the eyepiece.
