Explore the Cosmos in High Definition: Features a generous 102mm (4-inch) aperture and a versatile 660mm focal length to deliver bright, crisp views of the lunar surface, planetary details, and bright deep-sky objects like the Orion Nebula and Andromeda Galaxy.
Refined Celestial Tracking: Equipped with a manual German Equatorial mount (EQ20) complete with setting circles and dual-axis slow-motion control cables, allowing you to smoothly track objects as they drift across the night sky.
Completely Tool-Free Assembly: Engineered for simplicity and ease of use, the entire telescope can be assembled in minutes without any hand tools, letting you focus on the stars rather than the setup.
Fully Coated Glass Optics: High-quality optical coatings on the glass elements maximize light transmission, delivering enhanced contrast and sharpness for both nighttime astronomy and daytime land viewing.
Smart Device Integration: Includes a universal smartphone adapter compatible with major modern mobile devices (such as Apple iPhone, Samsung Galaxy, Google Pixel, Huawei, and others) alongside a Bluetooth remote shutter to easily capture shake-free astrophotography.
Wide Magnification Versatility: Supplied with three distinct 1.25-inch eyepieces (4mm, 10mm, and 20mm) and a 2X Barlow lens, offering a practical magnification range from 33x up to 330x to suit wide-field or high-power viewing.
Terrestrial and Astronomical Dual-Use: The included 90-degree erect-image diagonal corrects the viewing orientation, making this telescope as comfortable and effective for daytime wildlife and landscape observation as it is for stargazing.
Heavy-Duty Stability: Supported by a full-length, adjustable stainless-steel tripod that includes a convenient accessory tray to keep your eyepieces, lenses, and filters organized and within arm's reach.
Worry-Free Performance: Comes backed by a robust three-year manufacturer warranty, ensuring reliable performance and support for your intermediate stargazing journey.
