The 6mm Ethos offers a 100 degree apparent field and is an ideal for faster optical systems with focal ratios of f/6 or lower. 

TeleVue faced quite a challenge developing new Ethos eyepieces to the same performance standards achieved by the 13mm and 8mm models, perhaps the most honored in history. We hope the increased field of the 17mm and increased power of the 6mm will open up new visual experiences that Galileo could hardly have imagined, from small refractors to the largest Dobsonians.

If we may inject an editorial opinion here, the 6mm Ethos is most suited to telescopes with a focal ratio of f/6 or lower. This ensures an exit pupil of at least 1mm, which will provide a brighter view of those elusive faint fuzzies. As a matter of fact, we think that this represents a killer eyepiece for ultra fast optical systems with focal ratios of f/4.5 or lower, offering up bright images with a truly magnificent field of view.
