Discover the wonders of deep sky and planets with the Sky-Watcher Black Diamond 120ED telescope. Designed to provide exceptional optical performance, this large aperture apochromatic telescope is ideal for astrophotography and high-precision visual observation.

Features:

• Optical formula: Apochromatic telescope
• Useful diameter: 120 mm
• Focal length: 900 mm
• Focal ratio: f/7.5
• Objective: Doublet with ED FPL-53 (Schott) multi-coated glass
• Focuser: 50.8 mm Crayford dual-speed (10:1) aluminum
• Material: Aluminum tube with blackened and baffled interior to limit stray light
• Weight (with rings and dovetail): 5.2 kg
• Tube dimensions (length x width): 920 mm x 140 mm

Advantages:

• High-Quality Optics: The ED FPL-53 glass reduces chromatic aberrations, providing sharp and contrasted images.
• Multi-Coatings: "Metallic High-Transmission" (MHC) for light transmission close to 99.5%, ensuring bright and detailed views.
• Precision Focusing: Dual-speed Crayford focuser for fine adjustments, ideal for astrophotography.
• Sturdy and Elegant Construction: Robust aluminum tube without plastic parts, with a black and white aesthetic design.
• High Brightness: A 120 mm aperture collects 2.25x more light than an 80 mm telescope, providing brighter and more detailed images.

Use:

• Planetary and Lunar Observation: Optimal performance for observing details on the Moon, Sun (with appropriate filter), and planets.
• Deep Sky Astrophotography: Ideal for photographing nebulae, galaxies, and globular clusters due to its short focal ratio and high brightness.

Quality Control:

• Ronchi Test: Each objective is tested to ensure optimal optical quality. The white and black lines should appear straight and parallel.
• StarTest: Checks the optics' ability to reproduce a point image from a point source, ensuring perfect centering of the objective.

Included Accessories:

• Rings with Vixen-style dovetail
• Kodak-thread screw for camera attachment

Notes:

• Maintenance: Avoid sudden temperature changes to prevent fogging on the lenses. Never look directly at the sun without an appropriate solar filter.

The Sky-Watcher Black Diamond 120ED telescope is a top choice for amateur astronomers looking to explore the sky with exceptional precision and clarity. Enjoy high-quality optics and robust construction for unforgettable astronomical observations and photography.
