Tele Vue Large Field Flattener for Tele Vue 101 or 127 IS Telescopes - LCL-1069

  • Tele Vue Large Field Corrector designed specifically for NP101is and NP127is telescopes.
  • Provides a flattened image field for both the 101 mm and 127 mm Nagler-Petzval APO refractors.
  • Enhances edge-of-field quality for imaging use.
  • Optimally suited for use with CCD sensors measuring 35 mm or larger.

Tele Vue 0.8x Focal Reducer Lens Body for Tele Vue NP Scopes - NPR-1073

  • Tele Vue Focal Reducer for NP and NPis series telescopes.
  • Reduces the effective focal length of Nagler-Petzval refractors by a factor of 0.8x.
  • Best suited for typical 55 mm back focal length SLR camera bodies that accept T-rings.
  • DSLR camera use requires a 2.4” adapter, while CCD camera use requires the proper spacing needed to maintain 55 mm of back focus.

Tele Vue Focal Reducer Body Adapter for 2" Focuser - RAD-1074

  • This adapter makes TeleVue focal reducers compatible with standard 2" focusers.
  • Enables the use of Tele Vue 0.8x Reducers (NPR-1073 or RFL-4087) on NP101, NP127, or TV102 telescopes.
