Doesn't the beam finder function, sort of concentrate the beam to a small
area on the screen, and thus less spread of the beam on the screen surface?

Sure, probably 1/2 in both X and Y. So, it would be much brighter. But I
got the impression - perhaps not valid - that the appearance was normal
for the beam finder but maybe he just meant the brightness was then adequate.
