Hi,

Reading the documentation that came with my new Nagler, I came across this:

"Tele Vue recommends choosing low and medium power eyepieces in ratios of field stop diameters. For example, factors of 1.4 or 2.0."

also:

"a decreasing factor of 2 (which results in a 4x decrease in area size)"

I'd be really interested to know, if field stop ratio has been a significant factor in eyepiece choice amongst members here, why a particular ratio has been chosen....it's one thing to read about it, but real-world experience is king, and if anyone could offer their thoughts I'd be most appreciative.

Cheers

Stephen
