Hi,

I just ordered my first primary mirror (10") for DOB from Coulter Optics.
I want to test it after it arrives. Does anyone has expirience with testing/checking params for parabolic mirrors?

If you feel so inclined to do so, then a http://www.telescopemaking.org/ronchi.html" [Broken] will do the trick.

Or, at first light any problems will become evident.

However, Coulter Optics I have found produces quality products.
