Re the idea of rifle scopes in the 1800s..I'm betting most don't realize how good some of these were back then. I'll give a personal description of a technology that is related, as this is where the rifle scopes were born from. Naval telescopes. Sea distances were pretty far, more than a typical land battlefield. Naval chases and battles were in the order of miles vs yards. Telescopes were considered very high tech back then, and often made the difference in preparation for battle...who can see who first.
So here's a French Naval Telescope I recently found at an estate sale. From the mid 1800s. It is a 40 POWER telescope.
I took it apart and cleaned it up. Now after 170 years, I didn't expect much, but luckily I live on a golf course(as everyone does here in Florida

), and I have a long distance in which to see the true acuity of the scope. I put my smartphone up to eyepiece as best I could, and held the long scope(all 40inches) as steady as I could and took these pictures. Now mind you, I'm holding a smartphone in one hand and the scope in the other at the time I took these. AND the truck and person were *moving* when I took the pictures. The fuzziness in the pics is some vegetation in the foreground near my house. I was truly shocked at the clarity.
I did some research on these scopes and found that the nice high power ones like this one sold in the order of 50 pounds sterling, which 170yrs later is equal to about $10,000US today.
The distance of these images is 710YARDS, almost half a mile. The last pic is of the distance. That small purple circle in the middle is the frame for the pictures.
