Description
Beginner stargazers looking for clean planetary views without noticeable color fringing rely on the Skywatcher AC 70/700 Mercury AZ-2 Telescope long-focus refractor system. Designed with an f/10.0 focal ratio, this 70mm (2.76 in) aperture telescope features a 700mm focal length, delivering 1.66 arcseconds Dawes resolving power and reaching magnitude 11.9 for lunar crater and planetary exploration.
The Skywatcher AC 70/700 Mercury AZ-2 Telescope utilizes an air-spaced Fraunhofer achromatic doublet objective with multi-coated crown and flint optical glass elements. Its 685mm aluminum tube features an unobstructed 0% central profile and a 1.25-inch rack-and-pinion focuser. Mounted on an AZ-2 manual alt-azimuth fork mount with an altitude micro-adjustment rod on an aluminum tripod, the 1.70 kg (3.75 lbs) OTA ensures steady, shake-free tracking of bright solar system objects.
Key Features of Skywatcher AC 70/700 Mercury AZ-2 Telescope
