Default Astronomy Magazine error?

Hi there. You posted:

I'm not sure about this one. Seems the latest issue reviews
some eyepieces. It says in one part that Nagler eyepiece has
little or no distortion. Have the new Naglers been corrected
for this?


Astronomy Mag has not been known for an extreme level of accuracy. I have
used the 31mm Nagler and it does have some pin-cushion distortion, although
otherwise, the star images are quite sharp from edge to edge. The distortion
isn't much of a problem unless you like looking at grid lines a lot :-).
Clear skies to you.

Rich,
It is all in their definition of "little distortion" ;-)
