Used the 14mm tonight with my new-to-me Skywatcher 200mm f/5 Newtonian. I'm no expert on reviewing eyepieces, but it performed superbly. Stars seemed sharp across the whole field. Occasionally I'd see a star near the edge that wasn't quite sharp, but this seemed to be due to my eye not being in quite the perfect position as a tiny movement would bring it back to sharpness. I also have slight astigmatism that may have played a part.
The main thing for me was the comfort of 20mm of eye relief. When I moved up to my 9mm Nagler T6 I felt I had to work a bit harder to get the best view. I have a used 13mm Nagler coming and I'll be keen to compare this with the Delos.
I'm glad I made this impulse purchase!
