TeleVue Mounting Rings
Mounting rings are sold separately for TeleVue "is" or Imaging System telescopes. Choose 4-inch rings for the NP101is or five-inch rings for the NP127is. TeleVue clamshell rings are included with their respective telescopes, but may also be purchased separately for use with TeleVue or other telescopes. The 3-inch clamshell ring fits the TV-76 and TV-85. The four-inch clamshell ring fits the NP101.
