We tried both the 26 T5 and Stephen's Pentax XW 30 in a couple of different scopes that night. There was a bit of scope to scope variation as always happens, but the general conclusion was that they are both great wide-field eyepieces, and most observers would be very happy with either one.
I am a great admirer of Pentax eyepieces, but the reason I went for the Nagler at the end of the day was mainly because of exit pupil considerations. The Nagler has a 5.6mm exit pupil in my 14", whereas the Pentax produces a 6.5mm exit pupil - just a touch too big for my average-sized eyes. And if it's good for taunting Doug with, then so much the better

It was a great few days at Snake Valley & we got our fill of galaxies in the Leo cluster. And Mimosa was looking splendid (I hear you, Les!).
