Sky-Watcher AC 70/500 Mercury AZ-2 Astronomical Telescope
The Sky-Watcher AC 70/500 Mercury AZ-2 astronomical telescope represents the ideal entry into the world of amateur astronomy. This universal achromatic refractor combines excellent optical properties with simple operation, making it a perfect choice for beginning astronomers of all age categories.
Superior Optical Performance
The telescope is equipped with a high-quality **achromatic objective lens** with a diameter of 70mm and focal length of 500mm, providing a light ratio of f/7.1. The 70mm achromatic objective can capture 36% more light than standard 60mm models, resulting in brighter and more detailed observations. The doublet lens construction effectively minimizes chromatic aberration and provides sharp images with good contrast.
The optical tube is made from aluminum alloy and finished in elegant white color. The total tube length is approximately 360mm, with a weight of around 2.1kg. Internal parts are black-painted to minimize scattered light. The objective lens is protected by a removable cap with integrated chain to prevent loss.
Reliable AZ-2 Altazimuth Mount
The AZ-2 altazimuth mount is known for its simplicity and reliability. It allows smooth rotation in both horizontal and vertical axes using fine adjustment knobs. The mount features adjustable friction resistance that ensures optimal balance between stability and ease of movement. The aluminum tripod is height-adjustable from 71-121cm and provides sufficient stability for observation.
The total weight of the system including mount and tripod is approximately 7kg, allowing easy transport and quick assembly. The mount is compatible with other smaller Sky-Watcher refractors, providing future upgrade possibilities.
Complete Accessory Package
The basic package includes two high-quality Plössl eyepieces - 25mm and 10mm - providing magnifications of 20x and 50x respectively. Also included is a 2x Barlow lens that effectively doubles magnification and expands observation possibilities to 40x and 100x. A 5x24 optical finder scope with crosshair reticle facilitates targeting of observed objects.
The 1.25″ focuser is equipped with rack-and-pinion focusing for precise adjustment and T2 threading for camera attachment. A 90° diagonal prism is included as standard equipment and enables comfortable observation of objects at high altitudes. All components are stored in a practical carrying case.
Versatile Observation Capabilities
The Sky-Watcher AC 70/500 is ideal for observing a wide range of celestial objects. The Moon reveals crater details, maria, and mountain ranges even at lowest magnifications. Planets like Jupiter, Saturn, Mars, and Venus show their characteristic features - Jupiter's bands and moons, Saturn's rings, or Venus's phases.
From bright deep-sky objects, you can observe globular clusters like M13, M3, or M15, open clusters like the Pleiades and Hyades, nebulae such as M42 in Orion or M57 in Lyra. Double stars like Albireo or Mizar provide beautiful color contrasts.
User-Friendly Design
The telescope is designed for easy use without requiring complex adjustments. The altazimuth mount doesn't require balancing like equatorial systems, significantly simplifying first steps in astronomy. The entire system can be assembled within minutes without tools.
