Does not meet the hype
This eyepiece was a disappointment, especially considering the $300+ price I paid.
On my 11 SCT, the views are wide, but heavily washed-out with internal glare. I had to recheck the stats to see if they claimed blackened edges on the glass. They do, but you wouldnt know it by the results.
The sharpness is acceptable on my 4.7 refractor, but is well below the performance of my Axiom eyepiece on the 11 SCT.
I will be selling the 12mm Nagler, and getting another lens.
