Yes, Dave. This is a new QC problem. I don't know if this "bubbles" can be seen on the old or gold objective models but, it is apparent in the clear bluish newer models. I recommend all of you to re-inspect your scopes every angle under sun-light......

Just to recap:: My first purchased PST from Discovery Store had about 70% "rust" right out of the box-see serial #99760.

When the new shipment comes in I'll update you all.

Richard: I'll find out the serial # tomorrow.

By the way, for all the locals who lives around NYC area, I had an excellent service w/ Adorama especially salesman name David F. Note: This was my first business w/ them. I'm not affiliated w/ Adorama just a satisfied customer.
