I see what looks like astigmatism. Others say it's near perfect to the edge. Again try see for your self. 30mm Pentax XW is much much better IME but it is more expensive. 20mm T5 Nagler is great also, so I assume the 26mm would be also. 13mm T6 is nice although I've grown fond of longer eye relief, i.e. Pentax XW, Vixen LVW. 12mm T4 has long ER...
bottom line, at the premium end a lot comes down to personal preferences, so you really need to go out and try EPs for yourself see what suits.

I'll second all that Steve said here.
When starting out down this road, start with the eyepiece thats going to get the most use. For dso viewing that would normally be an ep that gives around 2-2.5mm exit pupil. Whether you choose the pentax 10mm xw or the nagler 13mm will depend on how much eye relief you like. For mine, the pentaxs cant be beaten for viewing comfort and excellent performance.
