I just read another post today stating that some of these scopes had scratched or dirty lenses. Has anyone heard of this?


It may have been a post I made, but my WO Star showed up with a scratch on one of the inside elements.  I sent it back and my vendor inspected their stock one and found similar scratches.  They offered me a few options and I'm going to wait for a new one from WO.  I'm still optimistic. 


The confusing thing is that WO published some specs in regards to scratch tolerances.  They are saying it comes from coating.  I don't think my scratch came from coating.  I didn't need a flashlight to see it.  I was able to photograph it below with my iPhone in one hand and it in the other.  The scratch is in the center. 



Here's a picture or two...

Doesn't show the scratch, but shows the lenses...

It may have been your post. I've had one since the first release date and haven't noticed anything. Then again, I never inspected that closely. I will though. I haven't noticed anything in my images that I can tell.

I bought mine from Agena, and Manish said he inspects each one, and he sent a few back to WO that had scratches.  I would beware of the flashlight test, as it's not a fair way to judge a scope, but if the scratch is truly meaningful your vendor probably shouldn't have sold it.


Also beware of moisture around these scopes.  Somehow the front elements are not sealed, so moisture can get inside on a really dewy morning.  Mine were actually in a brief rain shower, and the water got between the elements.  William Yang was terrific to work with in getting them repaired, but they had to go back to China for a few weeks for that.  Now they are better than new, but I make sure to keep the dew heater turned up!
