wavefront p.t.v. 1/3.203
wavefront RMS 1/14.4
Strehl: 82.7 %
at 532 nm

its a rather long report and will not fit on one side.

do you really want to see it from the poor sample ? The other samples are again on the way to the customers, so a good sample can be tested only early to middle of March to show the diffrence

Here I post a picture of the first sample of our new Tubedesign for future

its a 6"F/8 TMB

If I pay big Bugs for 4", than I want to get what is promissed and dont want to see that another 4" scope show visible clearly better finest details, I am wrong with that ?

Its fine for anybody else, if he is happy with what he gets, but it does not mean, I have to be happy too , correct ?

And if a specific scope is called the best and most perfect optics, but it does not show that in real live in any samples we ( not only me ) saw till now , than something is wrong with that claim, sorry

I never saw a thread from owners here reporting about the super planetary Maksutov Newtonians MN 68 with 15% C.O. and the MN 78 with only 13.5% , why ?

None have one in USA of this Planetary Killer Telescopes ?
