Yes the Nagler and pentax eyepieces are superb. Finding which is better is a personal choice imo.
But I do agree with Tony, the Vixen LVW is right up there in the high end eyepiece market.
You can pay half the price at the moment as Tony said, of the so called big two. But I think Vixen LVW’s are tops for value for money.
It’s just a pity Vixen does not have a 30 mm LVW.
