The Tele Vue-NP101(Nagler/Petzval) represents our closest realization yet of the "ideal" multi-purpose
photo/visual telescope. Its snap-to-focus sharpness across even the widest true fields, and rich
planetary contrast will take your breath away. Its quality, easy set-up, and airline portability
beckons your use. Over 20 years ago we reinterpreted the incredible design flexibility of the Petzval
portrait lens into an astronomical objective. No other design type affords the freedom to
simultaneously correct for: coma, astigmatism, field curvature, secondary spectrum, spherical
aberration, and spherochromatism. The artful combination of materials and design bestows the Tele
Vue-NP101 with diffraction limited performance into the furthest reaches of the visual spectrum.
Manufacturing advances in lens finishing, including interferometric monitoring of all surfaces, and
Tele Vue's stringent assembly and quality control, insure uniformly excellent results with every
telescope, and a level of manufacturer direct service all too rare. If your interests range from
terrestrial to rich-field or planetary astronomical, or to photography, just put in your eyepiece or
attach a camera and the NP101 is ready to satisfy right out of its case.
