Thanks Mark,
many people have given positive comments with this eyepiece I've noticed. Have you tried it in your Refractor yet? I wouldn't be surprised if edge correction was better in this scope. I have a 30 XW and find it pretty good even at the edge of field with scopes from 900mm FL and up. I wonder how the XW40 compares with yours?
Enjoy the views and clear skies
Nick
