     Yes, I took that into account, but no, it's something else,
like a slight graying effect coupled with my having to concen-
trate a bit harder, but not as much as that would seem to imply.
Again, the difference was slight, yet one to be expected given 
a dedicated magnification versus one arrived at in conjunction
with a barlow.

However, the increased field of view just compensated for the 
slight image deterioration, so I'm pleased.
