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

Engineered for exploring lunar craters, Jupiter’s moons, and Saturn’s rings, this 70mm Sky-Watcher Mercury refractor telescope pairs an f/10.0 focal layout with an AZ-2 fork mount. Its altitude micro-adjustment rod and 2x Barlow lens deliver sharp, high-contrast views for entry-level astronomers.

  • 70mm (2.76 in) clear aperture with 700mm focal length and balanced f/10.0 focal ratio
  • Air-spaced Fraunhofer achromatic doublet objective using crown and flint glass
  • Multi-coated optical elements with 0% central obstruction for high contrast
  • 1.25-inch single-speed rack-and-pinion focuser for precise visual focusing
  • AZ-2 manual alt-azimuth fork mount with altitude micro-adjustment rod
  • Lightweight aluminum tripod with integrated central accessory storage tray

  • Super 25mm and Super 10mm eyepieces included for versatile viewing magnifications

Fraunhofer Doublet Optics & Low Color Distortion

The 700mm focal length suppresses chromatic aberration effectively, delivering sharp, well-defined planetary disks and high-contrast views of lunar maria. Featuring an unobstructed optical train, this Sky-Watcher refractor supports magnifications from 10.0x up to 140x.

AZ-2 Fork Mount & Complete Visual Accessories

Simple manual pointing makes night sky navigation enjoyable for beginning astronomers. The Sky-Watcher Mercury 70 includes an AZ-2 fork mount with an altitude micro-adjustment rod for smooth vertical positioning. Supplied with two eyepieces and a 2x Barlow lens, it provides multiple magnification options for celestial observing and daytime terrestrial spotting.

  • AZ-2 alt-azimuth fork mount with altitude fine-adjustment rod for steady pointing
  • 1.25-inch 90-degree star diagonal paired with Super 25mm and 10mm eyepieces
  • 2x Barlow lens included to double the magnification capability of any eyepiece
