Tele Vue - 21mm Ethos Okular
The 21mm is the fifth eyepiece in the Ethos range with an incredible 100° apparent field of view. The direct comparison with a nailer is amazing. A nailer on the other hand looks almost like an eyepiece with too small a field of view.
The test on the fast Newton system led to the same result as with the other Ethos eyepieces: The edge reproduction is unbelievably good. At 82° it surpasses a typical nailer and even at 100° you have at least as sharp stars as a nailer at 82° field of view.
