Tele Vue Optics TV-NP101is OTA:

Unmatched Performance in APO Refractors

  • 30 Years of Excellence: Tele Vue has consistently led in developing APO refractors and eyepieces, reaching the pinnacle of performance.
  • Renowned Quality: Celebrated in the Backyard Astronomer's Guide for unrivaled optics, and chosen by Sky and Telescope for their significant SBIG STL11000 CCD camera review.
  • Advanced "is" Versions: The Tele Vue-60, NP101, and NP127 "is" versions maintain exceptional wide field and planetary visual capabilities, enhanced for easier and more flexible imaging.
  • Optical Perfection for Imaging: Redesigned to optimally serve up to 50mm diagonal chips without compromising visual performance.
  • Imaging System Scope Capabilities: Includes Focusmate Driver and Digital Indicator Kit, ideal for DSLR cameras on mounts like the Vixen Sphinx.
  • Redesigned Optical Systems: The NP101 (540mm, f/5.4, 4") and NP127 (660mm, f/5.2, 5") feature 4-element systems with larger rear lens groups to minimize vignetting.
  • Larger Focuser and Draw Tube: A new 3" front aperture and 2.4" rear aperture focuser eliminates light cone restrictions, capable of holding 12 lbs. while offering fine focusing control.
  • Versatile and Precise Focusing: Quick transition from visual to imaging operation with full camera rotation, plus residual focal plane tilt correction and repeatable focus measurement capability.
  • Innovative Imaging Insert Ring: Ensures squareness to the optical axis with three lock screws and compatibility with Tele Vue's Imaging System accessories.
  • Focusmate 10:1 Focuser and Accessories: Offers ultra-sensitive adjustment, measurable with an optional Digital Micrometer Kit, and electronic motor control with the Focusmate Driver.
  • Tele Vue's Commitment to Quality: Continues to create visual and imaging instruments that exceed expectations, backed by dedicated local machinists and in-house staff.
