Geez, I know the Synta ED80s are amazing scopes when used visually (for 80mm scopes) and people have produced wonderful images with it. I have not used the Megrez or anything in that league but the thought of spending $2000+ on an 80mm scope makes me cringe but if you're rich, you might as well get the best. But then why not spend a little more and get a Tak Sky-90?
