The Ethos I had on order through a local store came in a few days ago. Given the mediocre seeing and so-so weather--the new 'scope curse apparently applies to new eyepieces, too
)--I've only been able to do some casual observing with it the past couple nights.
That said, here are a few general comments. The eyepiece itself is about the same overall length as a T5 31mm Nagler, and the same overall diameter as a T4 22mm Nagler. Weight-wise it's slightly less than the 1.5 pound 22mm Nagler, definitely not as heavy as one would think given its physical size.
Looking through the Ethos in daylight, I did see some pincushion distortion, but this is not apparent at night. Very little lateral color (my target for this was the Moon). Easy to focus in all scopes tried so far (Tak TOA-130, TEC 140, TV85, etc.), crisp images, some *slight* reduction in that crispness toward the edges.
The AFOV is, simply put, amazing. 8O
Lots of positive comments from some of my fellow Denver Astronomical Society members who had a chance to look through it in my scope or theirs during Saturday night's DAS monthly open house. It certainly had lots of wow factor.
I'm definitely looking forward to trying this new EP under dark sky conditions, with fewer clouds and better seeing. Also looking forward to hearing users' comments on the Ethos.
