All models have 1¼" barrels and are parfocal with Tele Vue's 1¼" Plössl, Panoptic, Nagler, and Delos eyepieces. Named DeLite because that best describes the viewing experience, the name also recognizes designer Paul Dellechiaie's work. The DeLite series is a delightful addition to Tele Vue's visionary line of eyepiece developments.
