Rob, if what you're saying is correct about XW having better contrast than the Nag, why would respectable and experienced people Mike and John, and cloudynights reviews not say so, and why would they all put the Nagler on top. Or are you saying you are better than all these people with many more years of experience than yourself (at least between them).

Psst Rob over ere, just between you and me, I think the 13mm Nagler puts too much scattered light in the centre of the field of view on planets. Eg: in my 8" Dob, Mars is surrounded by a disk of light spanning about half the field of view. I would not recommend this EP for planetary viewing. But, then again, if you want an 82 degree FOV EP for planets, what else will work as well as a Nagler? ... I ordered the very-narrow field 12mm UO HD ortho for less than 1/3 of the price of the Nagler. I'm just curious to see how good the other end of the design philosophy scale is.
