Martin had the very bad luck of a defective main mirror. The out of focus star image (donut) had a spiral pattern in it. He sent the whole scope back and PWI replaced the primary (I doubt they would have argued much!). The main annoyance for him was that it was a remote setup, I can sure relate to that!
I never heard what the cause of the defect was, but Greg is implying that it was shipping damage to the primary? I find that interesting, and perhaps plausible, since I had never seen such a severe and strange defect star pattern before, and would have thought that basic QC would have easily picked this up.
