Sky-Watcher AC 70/700 Mercury AZ-2 Astronomical Telescope
Overview
The Sky-Watcher AC 70/700 Mercury AZ-2 represents the ideal entry gateway into the world of astronomy for beginning observers of the starry sky. This classic achromatic refractor with a 70mm aperture and 700mm focal length offers an excellent price-to-performance ratio, which has earned the trust of thousands of astronomical enthusiasts worldwide.
Optical Performance
The 70mm diameter objective provides a light-gathering power of f/10, ensuring sharp and high-contrast images with minimal chromatic aberrations. This configuration is optimal for planetary and lunar detail observation, where sharpness and image contrast are paramount. The telescope's light-gathering capability is increased 100 times compared to the naked eye, allowing you to see stars down to magnitude 11.0.

Mount and Stability
The telescope is equipped with a robust AZ-2 altazimuth mount, specially designed for beginning astronomers. This mount allows smooth telescope movement in all directions using fine controls on both axes. Operation is intuitive and doesn't require complex polar alignment setup like equatorial mounts. The aluminum tripod with adjustable height from 67 to 117 cm provides a stable foundation for observation.
Mount Features
- Type: Altazimuth (AZ-2)
- Slow motion controls on both axes
- No polar alignment required
- Adjustable aluminum tripod
- Height range: 67-117 cm
- Quick setup - no tools required
Observation Capabilities
Planetary Observation
The Mercury AZ-2 excels at observing lunar craters, mountain ranges, and other lunar features with amazing detail. On planets, you can observe Venus phases, polar ice caps on Mars, bands and spots on Jupiter including its four largest moons, and Saturn's magnificent rings with the Cassini Division.
Deep Sky Objects
Under favorable conditions outside the city, the telescope can display bright objects from the Messier catalog. Among the most beautiful are the Great Nebula in Orion (M42), the Pleiades (M45), the Andromeda Galaxy (M31), and the globular cluster M13 in Hercules. These objects provide a fascinating view of the diversity of cosmic formations.
Included Accessories
The telescope comes with essential accessories including two eyepieces (25mm and 10mm) providing magnifications of 28x and 70x. A star diagonal facilitates observation of objects high in the sky and corrects the image orientation. A 5x24 finder scope helps quickly locate desired objects in the sky.
Standard Equipment
- 25mm eyepiece (28x magnification)
- 10mm eyepiece (70x magnification)
- 90° star diagonal
- 5x24 finder scope
- Adjustable aluminum tripod
- AZ-2 altazimuth mount
Portability and Ease of Use
The total weight of the assembly is only 4.4 kg, making it an ideal travel telescope. It can be easily transported to observation sites outside the city, where the sky is darker and allows observation of fainter deep-sky objects.
The Sky-Watcher Mercury AZ-2 is designed with emphasis on ease of use. Telescope assembly takes just a few minutes and requires no special tools. The altazimuth mount eliminates the need for polar alignment, which can discourage beginners from astronomy, while still providing sufficient stability and accuracy for most astronomical observations.
Investment Value
This telescope represents an excellent investment in the astronomical hobby, allowing you to discover the beauties of the universe without the need for high initial costs. Its versatility and reliability make it an instrument with which you can grow in your astronomical skills.
