Refractor Telescope Sky-Watcher Mercury 70/700 AZ2 140x Black

The Sky-Watcher Mercury 70/700 AZ2 is a manual refractor telescope engineered for entry-level astronomers and hobbyists who want reliable visual observation of the Moon, planets and brighter deep-sky objects. Its 70 mm aperture and 700 mm focal length form a compact optical tube that balances portability with sufficient light-gathering power. The model includes an alt-azimuth AZ2 mount and a lightweight aluminum tripod for straightforward setup and steady tracking during casual observing sessions.

Advantages

The optical design of this refractor provides crisp, high-contrast views with minimal maintenance because the lens elements are fixed. Its 70 mm objective delivers a practical combination of brightness and resolution for lunar and planetary details as well as for star clusters and some nebulae. The AZ2 alt-azimuth mount offers intuitive up/down and left/right movement, making it easy to point and follow objects without complex alignment procedures. The included aluminum tripod is lightweight yet stable enough for field use and transport to observing sites.

Suitable for

• Beginner stargazing and learning basic telescope operation
• Observation of the Moon and planets (Jupiter, Saturn, Mars)
• Viewing brighter deep-sky objects such as open clusters and nebulae
• Educational demonstrations and amateur astronomy clubs
• Portable use at parks, backyard, or travel observing sessions

Key specifications

• Optical type: Refractor (achromatic)
• Aperture: 70 mm
• Focal length: 700 mm
• Maximum useful magnification: up to 140x (dependent on seeing conditions)
• Mount type: Alt-azimuth (AZ2)
• Tripod material: Aluminum (lightweight, adjustable)
• Eyepieces: Includes standard eyepieces to achieve common magnifications
• Finderscope: Simple aiming assistance for target acquisition

How to use

Set the telescope on a level surface and extend the aluminum tripod to a comfortable height, then attach and secure the optical tube to the AZ2 mount. Start with a low-power eyepiece to locate targets using the finderscope, then center the object in the main eyepiece and switch to higher magnification if atmospheric conditions allow. Use slow, smooth motions on the alt-azimuth controls to track objects across the sky; for terrestrial viewing, point and focus in the same manner. Allow the instrument to reach ambient temperature before detailed observation to minimize image distortion.

Usage recommendations

For best results, observe from a dark location with stable atmospheric seeing; use low to medium magnification for most deep-sky objects and higher magnification for lunar and planetary detail when the air is steady. Protect lenses with caps when not in use and transport the telescope in a padded case to avoid misalignment or damage.
