Re: 1/6 or 1/8 wave

I've seen a couple of Intes MK66's advertised - one 1/6 wave and the
other
1/8. The 1/8th should be better, but could someone give me an idea of
what
the visual difference between 1/6 and 1/8 might be? Is there an obvious
difference in image quality? And would either of these be all that
different from, say, a Celestron or Meade 8" SCT or 7" MAK or even the
Orion 150mm MAK?

Check out http://www.rfroyce.com/compimag.htm for an interesting
comparison.


Dennis,

I have a poster from AstroQuest that shows a similar comparison through an
8" scope, with additional comparisons of various secondary obstructions.
I've done a fair of observing with good 8" and 10" scopes, and I don't think
either the web site or the poster quite convey the amount of detail that can
be seen under steady skies.

Clear skies, Alan
