Tele Vue Optics TV-NP127is OTA:

The Pinnacle of APO Refractor and Imaging Technology

  • Decades of Optical Excellence: For 30 years, Tele Vue has been at the forefront of APO refractor and eyepiece technology, achieving unparalleled performance.
  • High Acclaim in Astronomy: Praised by Backyard Astronomer's Guide for unmatched optics, and chosen by Sky and Telescope for testing the SBIG STL11000 CCD camera.
  • Innovative "is" Series: The Tele Vue-60, NP101, and NP127 "is" versions retain their superior wide field and planetary visual capabilities, now enhanced for more versatile imaging.
  • Optimized for Imaging and Visual Use: Designed to be perfect for imaging up to 50mm diagonal chips without compromising visual operation.
  • Advanced Optical Systems: The NP101 (540mm, f/5.4, 4") and NP127 (660mm, f/5.2, 5") feature redesigned 4-element systems to minimize vignetting and ensure edge-to-edge clarity.
  • Upgraded Focuser and Draw Tube: Newly developed larger focuser and draw tube with 3" front and 2.4" rear apertures eliminate light cone restrictions, supporting up to 12 lbs. and allowing fine focusing control.
  • Versatile and Precise Adjustments: Quick transition capability from visual to imaging operation, with full camera rotation and no focus change, plus focal plane tilt correction and repeatable focus measurements.
  • Secure and Accurate Positioning: The draw tube includes three lock screws for maintaining squareness to the optical axis, accommodating a range of Imaging System accessories.
  • Sensitive Focusing Mechanism: Features the Focusmate 10:1 planetary ball type reduction focuser for ultra-sensitive adjustment, with optional Digital Micrometer Kit and Focusmate Driver for electronic control.
  • Tele Vue's Commitment to Quality: Renowned for producing visual instruments beyond expectations, Tele Vue continues this tradition with its advanced imaging equipment, backed by dedicated craftsmanship.
