Siegfried would be the one to ask about the Clave's as he has a few I believe. I'm not sure if it was the Clave eyepiece or Siegfried's new Mini-Clark (TEC-200) itself but the combination gave some incredibly sharp Lunar views at one of the last Harmon's star parties. No planets were out at the time and we were under the glow of the city and parking lot lights so I can't comment on contrast and the like. dlb On Friday, January 17, 2003, at 08:57 AM, Chuck Hards wrote:
Brent, the last time I looked through a Clave', there was no such thing as TeleVue, and I wouldn't trust my memory at this point to draw a comparison. The Clave's were tack-sharp, however.

I haven't looked through the radians, nor the TeleVue Plossls. How do they compare to the Clave Plossls?

I have found hat the best eyepieces are the orthos for high
power.
A
good ortho will outperform a plossl 95% of the time.
A bad ortho will not fare as well.
Absolutely on-track, Brent.
I have also used the 4.8mm Nagler on my 10" along with a 2.4X Barlow. I didn't like the spurious reflections I got both with and without the Barlow. I believe this comes from the Nagler's numerous elements.
Here, I would think that the Nagler is out of the running on sharpness alone. The ortho has better resolution. But honestly, Brent, the TV Plossls
are
the sharpest I've looked through, at least for the focal lengths used. Have you checked them out? As for Orthos, I prefer the good-old UO Orthos, my favorite is the 9mm. What about those TV "tack-sharp" eyepieces. "Radians", IIRC; are they as sharp as advertised?
