Tele Vue NPF-5055 overview

  • 1Description

The product of a corroboration between Tele Vue Optics and Finger Lakes Instrumentation (FLI), the NP127fli f/5.3 Astrograph APO Refractor Telescope is a purpose-built wide-field astro-imaging optical tube assembly (OTA) made to specifically work with FLI's ultra-precise Atlas Focuser, CenterLine filter wheel, and ProLine imaging cameras. Since the designer's intent was to create an astro-imaging instrument its performance has been engineered with an emphasis on superior performance featuring a 127mm aperture, 680mm focal length, and a fast f/5.3 focal ratio.

The telescope's Nagler-Petzval refractor optical configuration was designed by Tele Vue's founder Al Nagler with its objective consisting of five lens elements set in three groups configured with a two-element full aperture objective in the front and a two-element sub-aperture doublet set back in the optical tube. The NP17fli has a built-in Tele Vue Large Field Corrector lens that corrects for chromatic and spherical aberrations to produce clear and crisp images with true color rendition across the entire field of view. An image plane correction system enables all objects through the entire depth of field, no matter their distances from each other, to be brought into perfect focus.

Tele Vue and FLI have designed an imaging system that not only produces superior images, but is uniquely capable of handling large imaging rigs. These large rigs can have multiple peripherals such as filter wheels, off-axis guiders, and CCD cameras; and the often uneven weight distribution can lead to damaging torque on delicate focusers and OTAs. The NP127fli was conceived, designed, and built to eliminate these problems and provide an imaging platform that can handle complicated rigs without a problem.

The OTA has been specifically designed to perfectly position the FLI Atlas focuser near the center of its travel, and the Large Field Corrector lens sits within the Atlas and is properly located to accommodate the combined path length of FLI's CenterLine filter wheel and ProLine cameras
