Well, even though scope time has been a bit limited I've had a chance to spend some time looking through my new 13mm T6 Nagler, and I'm very very very happy with this eyepiece
The contrast and crispness of the views are beautiful, and the large FOV means I spend less time nudging the dob...it's taken a little time to get the feel of the eye relief, but now it's no problem and I'm finding it very comfortable.
Overall, WOW!
(the only possible downside is now i've begun to think i might need a better focusser...
)
