Discover the wonders of deep sky and planets with the Sky-Watcher Black Diamond 120ED telescope. Designed to deliver 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) in aluminum
• Material: Aluminum tube with a 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

Benefits:

• High-Quality Optics: ED FPL-53 glass reduces chromatic aberrations, providing sharp and contrasted images.
• Multi-Coatings: "Metallic High-Transmission" (MHC) for near 99.5% light transmission, ensuring bright and detailed views.
• Precision Focusing: Dual-speed Crayford focuser for fine adjustments, ideal for astrophotography.
• Solid and Elegant Construction: Sturdy aluminum tube with no plastic parts, featuring an aesthetic black and white design.
• High Brightness: A 120 mm aperture gathers 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 of the Moon, the Sun (with appropriate filter), and the planets.
• Deep Sky Astrophotography: Ideal for photographing nebulae, galaxies, and globular clusters thanks to its short focal ratio and high brightness.

Quality Control:

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

Included Accessories:

• Rings with Vixen-style dovetail
• Kodak-threaded 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 an excellent instrument for amateur astronomers wishing to explore the sky with exceptional precision and clarity. Enjoy high-quality optics and a robust construction for unforgettable astronomical observations and photographs.
