Hi Paul,
I remember it being a lot harder the last time I tried to get a picture of the mirror- unfortunately, its pixelated- I'll try again with zoom. The spots you see in this image are on the actual surface of the mirror. You can't see anything when you use the scope, but I assume they are reducing the light transmission at the very least.

ok, here it is with more zoom.

My best guess is, that living in A/C in Singapore, I sometimes didn't let the scope reach ambient before unboxing it for use. Moisture condensed on the cold mirror and whatever was in it has etched the mirror surface.
Kind Regards,
Brad.
