Hi Chuck,
I think that SV scopes are very good, but much too expensive. My 5"
f/9.3 ($238) will outrun any SV scope short of the TMB/SV 6" APO. The
new Orion ED80 should outperform the Blackhawk.

Arguing witha Stellarvuite is akin to arguing with a religious
fanatic. No common ground will be achieved.

Hi Dave,

I did my homework. SV was selling scopes with reduced aperture and claiming
the reduced color was because of a "proprietary" design. They quit when they
got caught. Then they applied MV filters to the objective. Then they claimed
it was "attenuated" and not filtered (Sounds like Clinton and not having
"sex.") They also claimed the reduced color was due (again) to "proprietary"
design. That was BS. It was filtered --- pure and simple. There is nothing
wrong with using an MV filter coating. But there is something wrong with MV
filtering and claiming you are not doing it. Two months ago I was with an SV
owner. He insisted it did not have an MV filter and he knew this for a fact
because SV told him. But the coating was there.

Those are the facts.

Regards SV, the problem is you never know what Stellervue is doing to
reduce
the color. For a while they were stopping down the aperture (see Ed
Ting's
review). Then they went to applying an MV coating to the objective and
calling it a "proprietary" and "attenuated design" rather than admitting
they were filtering it. The last SV I saw had an MV filter applied to
the
objective, but the owner insisted it didn't because SV had told him so.

Aside from filtering or stopping down the aperture, unless you use
different
(and more expensive) glass, you aren't going to reduce the color,
regardless
of the "zonal control" g you achieve.

Chuck:

You're way behind the times and terribly misinformed there my friend.
The "stopping down the aperture" scenario affected ONLY the first 6
months of scopes produced and Vic indicated to his customers (I was
one of them) that there existed a problem with the 1 1/4" version (NOT
the 2" focuser version). Once the problem was resolved, he allowed
customers to send back their scopes for a retro-fit. For free. This
was WAY back in 2000. Very, very old news.

Now, as for the "attenuated design", this applied ONLY to the 102D and
not any of the other scopes Stellarvue produced. Sorry to disappoint
you there. The website, group site, and Stellarvue all indicated that
the minus violet coatings were only appled to that specific design
(102D) with the intent of reducing color. The latest version does not
have this coating, as Vic decided that it's easier (and less
expensive) to simply offer a filter that provides the same affect. It
was an interesting design and apparently worth the effort given the
reports provided by purchasers of the scope. Again, you're a bit
behind the times.

Try doing your homework before posting something intended to be
informative.
