Description: | The Meade 178ED is the world's largest continuous-production apochromatic refractor. Armed with 38.5 sq. in. (249 sq. cm.) of precision, unobstructed light-collecting area, the 178ED shows many objects in sharp, high-definition detail that larger telescopes of other types often fail to show at all. A series of ten field stops, mounted continuously along the inside surface of the main optical tube and included with all Meade ED models, combines with the industry's most advanced Super-Multi-Coatings to yield extremely high-contrast images at the focal plane. And yet, even when equipped with the state-of-the-art Meade #1697 Computer Drive System, the telescope is within the budget of many advanced amateurs. Once you've experienced a Meade 178ED/APO, there can be little comfort in using a lesser instrument ever again.
