i currently own a ETX60.
When using a flashlight test, i discover that the inner flip mirror is very dirty. What appears to be smugs, dust and some minor scratches where present.
And the front lens too were cover with white secks that looks like dust all over the lens.
But when using the scope to view strutures they look ok, i can even see the air-cons grills in find detail in 1 football-field distance away.

Hi,
Don't worry about that. This is quite common and you can ask around and I think most of the scope owner will tell you that the lens and mirror on their scope also have this on it. Anyway, it won't affect the performance of your scope.
By the way, most lens and mirror will fail this type of flash light test.
Have a nice day.
