Details
Sky-Watcher Quantum top of the line ED-APO refractors offer premium optical performance for discriminating amateur astronomers and imagers. Refractors are coveted for their high-definition, superb for observing optimal detail planets and binary stars while delivering the contrast needed to see faint nebulosity against a coal-black sky background. Quantum refractors utilize the most modern optical glasses and fabrication techniques to deliver the ultimate in high-fidelity astronomical imaging. Each lens element is individually inspected for purity and absence of striations and other image-degrading imperfections. Every lens is pitch polished to exacting standards of optical fabrication and performance by highly skilled opticians and tested on an optical laser bench to rigidly controlled optical standards. The result is high-quality, diffraction-limited optics performing to the theoretical limits of their respective aperture sizes.
Includes full accessory assortment:
- 28 mm eyepiece w/ 2" barrel diameter, fully multi-coated optics
- 2" dielectric mirror star diagonal w/ 1.25" adapter
