The TeleVue NP127is is a premium 127mm f/5.2 apochromatic Nagler-Petzval refractor optimized for both visual observation and deep-sky astrophotography with large-format sensors. Its four-element air-spaced optical system delivers diffraction-limited performance with exceptional correction for field curvature, astigmatism, coma, secondary spectrum, and spherical aberration, producing a flat focal plane ideal for CCD imaging up to 52mm diagonal chips. The redesigned optical system with stainless steel front cell provides superior thermal stability and smaller spot sizes across a broader wavelength range, while advanced multi-coatings maximize contrast and light transmission. With its dual-speed 10:1 Focusmate focuser, longer dew shield, and imaging-optimized mechanical design, the NP127is excels equally at high-magnification planetary observation and wide-field deep-sky imaging.
