Telescope Bresser Optics Lyra 70/900 EQ-SKY

The Telescope Bresser Optics Lyra 70/900 EQ-SKY is a classic refracting telescope designed for both serious beginners and intermediate astronomy enthusiasts. Featuring a 70mm aperture and a 900mm focal length, this instrument delivers clear and detailed views of the Moon, bright planets, and prominent deep-sky objects. The optical design gathers sufficient light to reveal lunar craters and planetary details, while the included equatorial mount ensures smooth and precise tracking of celestial objects as they move across the night sky. With a complete set of accessories and educational software, this setup provides a comprehensive introduction to observational astronomy.

Advantages

The telescope offers stable viewing conditions thanks to its sturdy equatorial mount, which helps compensate for Earth's rotation during extended observation sessions. The 900mm focal length allows for higher magnification levels, making it easier to study planetary surfaces and lunar features in greater detail. The included Cartes du Ciel astronomy software enables users to plan their stargazing sessions, explore the night sky digitally from a computer, and identify constellations and stars easily. The rich supply of accessories included in the package ensures that users can start observing immediately without needing immediate additional purchases.

Suitable for

• Observing lunar craters, mountains, and maria in high detail
• Viewing major planets such as Jupiter, Saturn, and Venus
• Learning celestial navigation and night sky identification with software assistance
• Beginner and intermediate astronomical observations

When it may not be suitable

This telescope is heavy, with a total weight of 24 kg, which may make frequent transport to remote dark-sky locations challenging for some users. Additionally, the 70mm aperture has limitations when attempting to observe faint deep-sky objects such as distant nebulae and galaxies.

Key specifications

• 70mm optical aperture
• 900mm focal length
• Equatorial mount for precise tracking
• Total weight of 24 kg
• Includes astronomy software for PC

How to use

Set up the sturdy equatorial mount on a flat surface, ensuring the polar axis is aligned for accurate tracking. Attach the optical tube assembly securely to the mount and balance it using the counterweights provided. Insert the desired eyepiece into the focuser, starting with a lower magnification eyepiece to easily locate your target. Use the finder scope to align the main telescope with the celestial object of interest, then use the slow-motion control cables on the equatorial mount to keep the object centered in the field of view as it moves.

What to consider before purchase

• Verify that you have adequate storage space and physical capability to handle a 24 kg setup
• Consider whether your primary observation site has clear views of the sky
• Determine if you prefer a refracting optical system for planetary and lunar viewing

For the best viewing experience, allow the telescope to adjust to the outdoor temperature for a brief period before observing, and use it away from bright city lights to maximize optical performance.
