Thanks Mike
As you'd know, right now in fact, you do a fair bit of agonising over which EP to choose for planets.
I gave the 9mm Nagler very serious consideration but ultimately decided the extra FOV was unnecessary for planets and the eye relief in the Pentax was just too attractive.
I don't wear glasses so 10mm eye relief wouldn't have been too arduous, but we do love our creature comforts and 20mm makes for comfy viewing
