Jerry,
 Do the star test, if things are as good as the
numbers say you will have great views, even if it is only 4% of the total light....
Confirm the data, then pack that baby nice and safe and ship
"her" out to the coaters, WTG, sounds like you have a great
mirror, enjoy the views, I can only wish I had a 16" mirror, im green
with envy, good going.
