On the other hand a Nagler has a slightly larger FOV although the 10mm Pentax XW at 70 deg is perfect for most. I have used just about every premium eyepiece thats currently available new or second hand (I own most of em !!) and I rate the 10mm Pentax XW and the 13mm Ethos as the 2 best general purpose eyepieces currently available to the amateur astronomer.
My choices would be (assuming you don't wear glasses)
1) 26mm Nagler T5. It is a clearly better eyepiece than the 24mm Panoptic, in just about every respect. It's also a lot more money.
2) 13mm ETHOS
3) 10mm Pentax XW
Televue 2X Barlow.

Yes I should have made it clear in my first post I don't wear glasses, although I still prefer better eye relief as comfort factor (>15mm).
Nagler 26mm is indeed expensive
As you said probably for my untrained eye i wouldn't notice much difference...
Would it not be better choice to go for the powermate rather than the barlow? Thankyou.
