Telescope Reviews: Re: Apparent Brightness comparisons

Ed,

I've just responded to this over on Astromart.

Not that I wrote anything YOU don't already know !

It just seemed a good opportunity , particularly on THAT site , to comment on how these revelations COULD make something of a mockery of the "optical theorists" who were so swift to contest my practical experiences with very small exit -pupil binoculars such as 10 x 25s, which "in theory" may have provided "sufficient brightness" to make no difference for daytime viewing alongside say a
10 x 40 ,but which I insisted all along did NOT.

Yes , amongst many other things Ed., your tireless work on this vignetting issue has certainly provided SOME kind of "technical back -up" to what I was trying to say all along.

There were times when I felt similar to how General Custer
must have felt regarding this issue , but I'm even more pleased now that I stuck to my gun regardless of the crossfire and ceaseless bombardment.

Regards , Kenny.
