My overall experience was excellent as OPT gave great service and the Ethos gives beautiful views.
I got this eyepiece as a gift. I almost could not believe. This eyepiece is great. To own it means many nights of deep observing pleasure. I could recommend it to all who could afford it.
The best eyepiece I've every used. The 1.25 mount with optional 2 adapter means I can use it on any scope, from my personal 150mm refractor to the 14 at the local astronomy club. Great clarity and brightness.
What can I say that has not been said? One heck of an eyepiece. I took this baby down to the Everglades the other night and I felt like jumping into the eyepiece. The sky was so black, the stars so sharp, the FOV, endless. M42 was breathtaking, my best view ever!!! Cant wait to get another one to attempt binoviewing with them.
1. Always center an object for the best view. 2. The field edge is only good for framing the object. 3. Eyepieces >70 deg FoV are mega-ultra-hyper-uber wide angle. Accept that compromise in edge quality. How times change!
Scary , this eyepiece brings you there ! Falling in truly does describe the view with this eyepiece. The satisfaction received when viewing through binoculars is duplicated with only one eye with this one , I cant wait to get two of these side by side in a bino configuration ! I do not want to look into the milkyway , I want to STAND IN IT ...and with this eyepiece , YOU DO! Very comfortable and easy to use and after about 15 minutes with it , it is not there and you are in outer space :- , you and scope become one. I have absolutely nothing negative to say about this wonderful eyepiece and 13mm is a nice starting point .
