I have obtained a used Celestron/Vixen C102/1000 refractor.

It has a couple of strange attributes:

One is that it's white? I thought (and so did Celesctron Tech support) that they only made black C102s, even back in the 80s, when this scope appears to have been produced. It does NOT appear to have been re-painted, and has a large Celestron sticker on the side with some real 1980s style black letters!

The second pecularity is that it has what looks like "Newtons Rings" in the objective?

I have seen these on two optical flats in close contact, and it is in fact, a way to test for "flatness" of the glass in question as far as I know.

The images appear fine, and I'm not really sure if the two lenses in the Achromat are too close together, causing the rings to appear? (Pnched optics?)

The images appear to be rellay good so far, but the clouds keep coming in before I can star test it!

Any ideas?
