Honestly, I think if you need to "startest" the scope to find a defect then maybe it isn't a defect after all. That is the point of this thread, the practical difference between a high end mirror and a cheap one. I myself have a high precision mirror in my imaging scope, the main reason for which is that the price difference between a basic mirror and a "ultimate" one was nothing after shipping it here.
