Tele Vue Optics and Finger Lakes Instrumentation have teamed together to create a “turn-key,” wide-field imaging system dedicated to the astro-imager. The flat-field, fast focal ratio, and short focal length of the Tele Vue NP127fli Astrograph are a perfect match for the ProLine PL16803 camera. Together they produce over a 4° field of beautifully sharp stars!
The NP127fli has been designed to ideally position the Atlas focuser near the center of its travel. Tele Vue’s “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. All connections use FLI’s Zero Tilt Adapter system. Additionally, Tele Vue’s unique image plane tilt correction is incorporated into the new rear section of the NP127fli. In the final stage of the build process at Tele Vue, each scope is set-up so that the imaging train will be as close to perfectly adjusted as possible. User adjustability is built-in to allow for any possible differences between a customer’s existing pieces of equipment.
