" If there is a difference it is most likely seen in the Takahashi profit figures". In other words, they are very successful in elite branding. There probably was a time when there was a performance advantage but those days are gone.
I will try to find the article for you.
Of course the wolfs will be after me now for daring to question Tak supremacy.

And this comprehensive look at various objective materials in combination (note the Strehl figures from #15 onward).

Eddgie's examples of comparative Strehl figures for FPL-53 and Flourite are worth a look, see posts # 13 and 14 in the CN thread.
What i take from the chart is that any historical (or hysterical) flourite advantage is no longer relevant if your choosing FPL-53, even to my guide dog, |
So Glen......we have gone back to quoting the "Theoretical Sacred Scrolls" and some third hand comments.
So you have had look through a Tak ......once ?? more ...how long?...how many different Tak? Observing location and Conditions? Did you do extensive side by side observations with the same EP's and Diagonals on the same targets on the same night and location???
The fact is Tak produces both Flourite and FPL-53 scopes so a potential purchaser can buy what optical configuration best suites their purpose and/or their preference. So where is the argument for or against Tak given they offer both ??
In the link to the Telescope Optics test website .....and the table you refer to...the highest Strehl Ratio was a F10 scope ....so better corrected refractor due to FL and a great achievement......but still not comparing apples to apples in terms of FL's
In fact the next highest Strehl in that Table is the FPL53 -BSL7-FPL53 triplet and only one manufacturer in the world makes 2 versions of that design i.e. TAKAHASHI ....so how does that support your anti Tak argument !?!?!
Rohr Tests have shown TOA 150 samples with Strehls of .99 which again does not support your Tak bashing.
So can you please provide detailed information and real work practical examples to support your argument ???
Or is this just the case of some very poorly and misread bashing due to being disgruntled because some people make a personal choice to pay a little more for a Tak for that extra bit of mechanical and optical quality??
