Eon 120 interferometer results

Hi Guys,
OK many of you know that I obsess about my optics. I'm surprised that it took me so long to cave in but I did.
I sent my scope to the folks at OMI and here are the results.
Output Units: Waves
RMS 0.031
Peak-Valley 0.24
Strehl Ratio 0.96
Astigmatism 0.05 22.4 deg
Spherical 0.20
Scale -0.50
Wavelength 550.0 nm
Description Orion Eon, Itz Marcus
Date Tested Oct 10, 2008
Operator JCM
Comments Tested on the wavefront at 550
It is well into diffraction limited territory as I understand that .80 would still fit the bill.
Its PTV is a little better than 1/4 but it has a nice strehl which I understand is more important that the PTV.
The folks at OMI said that the scope should be a solid performer (which I have found it to be so)
Any comments appreciated (just don't make to much fun of my obsessing).

Sounds like an excellent lens! I would not worry about
the Peak-Valley. Strehl is the important number, and
0.96 is excellent.

Interesting!

How about posting copies of the Focaultgram, Ronchigram and the picture from the interferogram? That would complete the picture.

Hi All,

This is great but not surprising news. The Chinese have come a long way with optics. I recently bought the same SW120ED that Jim has and I'm having the same experience that he is. This scope has extremely well figured optics and star tests unbelievably well. I've been fortunate to own a few premium scopes, refractors, newts, and cats, and this Synta made scope holds its own against them all.

Clear Skies,

Steve
