Televue Ethos Eyepieces

High Quality Eyepieces with 100-degree Field-of-View

 

 

Ethos

The Ethos range of astronomical oculars (eyepieces) is Televue's latest attempt to surpass their own record in terms of field of view (FOV). These eyepieces are claimed to have a fully-corrected field-of-view of 100 degrees (!). Televue's prior Nagler line of eyepieces has an incredible 82 degree FOV, but are easily surpassed by the Ethos line. I had only a single Ethos eyepiece - the 8mm - which I eventually sold to fund my astro-imaging equipment.

Most recently, Televue has announced the Ethos-SX line of eyepieces (e.g., 3.7 mm), which is claimed to have a 110 degree field-of-view. TheFOV on these eyepieces is so large, that many people need to roll their eyes around to take in the entire view!
