76mm, f/6.3, APO (Doublet) Refractor. From astronomical, to spotting, to birding, the TeleVue-76 combines compact size with the APO optical performance of the TeleVue-85. The expansive 5.5° rich-field drizzles your view with delicate jewel-like stars, while the APO performance of the Nagler designed, fully multi-coated 2-element objective and optional 2" Everbrite diagonal produce natural stellar and planetary colour rendition even at the highest useful powers. Small size and lighter weight permit use of lighter-duty tripods for easy field carrying and transportation. The padded shoulder bag provides protection and room for the scope and six eyepieces. If your interests crossover from astronomical to spotting or birding, and you demand the ultimate in portable performance the TeleVue-76 is always waiting to deliver.
