Ok Star test conducted.

Aside from miscollimation, which I will have to attend to the following was observed:

- the exhibits no astigmatism
- no roughness in the figure via star test.
- no apparent turned edges or circular zones.
- diffraction rings were even and sharp all the way from the outside to the shadow of the secondary.
- stars were as sharp as in my 4 inch Tak at focus.
- no coma was seen to the edge of a 24mm pan optic.

In short, these optics were impressive at first light. The airy disk was easily visible at focus with a nice even pattern surrounding it.

From the star test I cannot see what all the fuss was about before hand. It might not be a 24" RC or CDK, but for 2.5K it looks quite reasonable.

Now for the imaging tests. Stay tuned.
