Question to Tom Back (an apo designer)

Dear Mr. Tom Back,

Will you be so kind to answer simple and straight question?
I believe, that many peoples out here, will be interesting to
know your answer.

The question: do you consider the following telescopes as not
APOs?

1. TV's TV-102 ED, TV-76, TV-85 apos
2. BORG's ED serie,
3. Star 130 ED from the AP
4. Vixen's ED refractors
5. ED Star (from Silver Star, and as you told us, of your OWN(?) design)
6. Expected Burgess apos of your design (promised 4-5 better corr.,
than in equivalent achromat, right?)
7. Showa ED apos
8. Pentax ED apos
9. Nikon ED apos
10. Meade ED APos (especially 102mm F/9)
11. TAKAHASHI FS serie apos.
12. SV's EDT


Which of them are not APOs?



Valery Deryuzhin.

P.S. I consider them all (except #12) as APOs, but of different level.

P.S. 2 I think, that Mr. Tom Back will not answer. But I hope.

This constant sniping is, in my opinion, providing little
information that could be used to adequately judge. Giving
a simple yes/no answer on existing telescopes would provide
no information for us to use the next time. I think the
contrived 150 mm aperture example (about f/9) is close enough
to the boundary conditions that I have seen to be up for
grabs... perhaps not, but that remains to be seen.

Valery, is this an APO or not? If not, what disqualifies
it?

Easy. Because there is no central obstruction.

LOL

But it also depends on the quality of the glasses you're wearing at the
time. Ouch.

Yet another cheap (anonymous) shot. Your mother would be proud.
Thassmaboy!

Get a life or get some nerve! And do sign your trivial posts so we
know whch particular idiot is the knee-jerk jerk. BTW: Unless I'm
mistaken, what you are groping for is ARSE! Not the innocent beast
of burden. But one never knows in cases like yours. g

I also noted one interesting sign of the SV's "fort" defenders - they
can't answer constructively, thay rather use words like "ass",
"asshole" etc.
As always. When no factual arguments, these deceptive peoples jump to
personal attack with quite specific list of words. ;-)

I personally think, that peoples, who constantly use such words,
mostly
well correspond to them theirselves.

Bwahhhhbwahhhbwahh. BWAHBWAHBWAHBWAH! Valery, you are a FUNNY guy! I normally
don't respond to you anymore, but that was so funny I just couldn't stay away,
so here it is: Pot, Kettle, Black.

Oh, and I know what "pizdoon" means too. YOU'RE A FUNNY GUY!!!!
