spotting scope question-specific

I am looking into a spotting scope. I am considering a Swarovski Habicht
model AT 80. I can not find any info that would tell me if it has ED
glass (Extra-low Dispersion). Does anyone know of an online source of
data that would say one way or the other? Also, perhaps someone here has
one and has the documentation that might say what the details are.

all on topic replys appreciated
