WOW! OMG! (and many "expletives deleted"!).

Forget about the 100-degree field (well...I know you can't but...), this is quite simply the finest eyepiece I've ever seen - period! Contrast, sharpness, light-throughput, etc. are all just amazing. There is simply NO ghosting or other internal reflections...the background is jet-black and the stars (even in my 28" f/3.66) are absolute diamond-points to the very edge!

I've owned and used all of the "gold standards" over the years and NOTHING I've seen can match this!

Along with about a half-dozen other observers we did "A/B" testing with other top-of-the-line 13 and 14mm eyepieces (M-51, Thor's Helmet and M-42 were the targets). EVERYONE agreed that the ETHOS seemed to add additional inches of aperture. The increased detail in all of the objects was instantly apparent!

As a bonus, the fine detail on Saturn equaled or exceeded the best "planetary" eyepieces any of us had ever used. And, again, NO ghosting or internal reflections. This baby does it all.

And, as for the 100 degree field, Vic said it best... "you feel like you're going to fall in"..."the scope just gets out of the way and it's like you're standing in space looking at the objects".

If I were only going to have ONE eyepiece (or one 'pair') THIS IS IT!
