I thought about it some more, Bill, and frankly it is impossible to "leave
aside the difference in aperture." The difference in aperture is by far the
overriding difference between the two scopes and there is no way to separate it
out in comapring theme, it is simply too great a factor.

As to your other questions, the figure and polish in both scopes are excellent.
There is some spherochromatism affecting the out of focus images using each
scope, so neither of them are easily evaluated for optical figure using the
handy dandy star test. I don't have a green interferometer on me, so...

Both scopes have very smooth, sharp optics that positively snap into focus.

>From what I know of Yuri and his boys, I think they lavish a great deal of
effort on getting the TEC lenses absolutely perfect.

>From what I've seen, I believe that TEC has developed a deep sense of personal
pride regarding the fact that they fabricate their optics "in house." Anyone
involved in producing a high quality product realizes that this pride is itself
is a fuel that drives the quest for perfection.

And while Takahashi subs their lens sets out to another company (a subsidiary
of Canon?) , they, too, obviously have optics that are fabricated to a very
high spec.

They are both great scopes.

In ending it is worth noting that I have not had the Tak out even once, even to
do a side by side, since having received the TEC two months ago.
