Tele Vue 21.0mm Ethos
With a 100 degree AFOV(Apparent Field Of View- 110 degree w/3.7 and 4.7mm versions), the view through a Tele Vue Ethos series eyepiece is more than 50% larger than an 82° AFOV. Essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.
