My front steps were at about "98% total" due to our location, and it was quite dramatic
(as it went very, VERY quickly from "somewhat dark"
to nearly "total moonless midnight dark.")
Of course, it went the other way after about 2 minutes.
We made no special effort to see it other than just step outside for about 5 minutes.
I had a pin-hole punched in a sheet of cardboard and projected a very small image on a
sheet of paper.
Litte effort and got a nice result... but, nothing that I'll "remember forever."
