TeleVue Panoptic
TeleVue Panoptic eyepieces offer a wide 68 degree apparent field and have been a long time favorite for low to medium power observing. The 19mm and 24mm editions have a 1.25-inch barrel format and are extremely popular for use in binoviewers. The longer focal length versions with their 2-inch barrel format present incredible low power wide field views, especially when combined with short focal length refractors.
