Tele Vue Ethos 21mm - 2" - 100° field
With 100° apparent field of view TeleVue sets new standards

The most important features of the ETHOS eyepieces:
very high contrast due to excellent multi-coating, inner and edge blackening.
a very comfortable eye relief, which makes the eyepiece suitable even for eyeglass wearers
high field sharpness, even in fast instruments



With an apparent field of view of 100°, the field of view is over 50% larger than at 82°. This clearly enhances the "spacewalk effect". The impression of floating in front of the object becomes overwhelming - this is a truly impressive experience. Another advantage is that you can observe an object for much longer without having to track the telescope. Especially owners of Dobsonian telescopes appreciate this.

The Ethos 21mm has a very large true field of view, approaching that of the 35mm Panoptic. The advantage of the Ethos 21mm is clear, you can achieve a larger true field of view in the sky with very fast Newtons while making full use of the light. For example, an f/4 Newtonian will provide light beams of about 5mm with the ETHOS 21mm. Ideal for observing in average light conditions. An eyepiece with 35mm focal length would already have a light bundle of 8.7mm diameter. A large part of the light would pass the eye unused.

"Perfektes Okular!!!"

Written by Philippe FABRE

"*** [En] An open window on the Universe. An undeniable comfort of use. A huge field. Whether for short or long focal length, the pleasure of rediscovering objects has amazed us. Tested on a T400 f / d 10 and T350 f / d 5 (without correction), the nights were magical. The color felt is neutral, on the T400 we did not see any coma. Be careful with the weight, it is 1.02 kg! No regrets of purchase, a real race beast."
