I did a simple test with my Burris Landmark 15x - 45x spotting scope today. The target was lettering on a neighbor's boatlift at a paced-off distance of 100 yards plus.
I could easily (no strain at all) make out letters that are .300 high with .078" strokes -- as in the width of an I or the stem of a T. I could read with "eye test" facility (read the smallest line you can see) characters that were .187 high with .045" strokes. I could easily discern individual blades of grass at the shore end of the dock.
I would think that it would be very easy with this
