Omegon Advanced X Dobsonian 254/1250 is a powerful 10" telescope designed for deep-sky observing, delivering bright, detailed views of galaxies, nebulae, and star clusters. With its large aperture and simple operation, it offers serious performance without the complexity of motorised mounts.

This Dobsonian telescope is built for ease of use — no alignment, no electronics, just smooth manual control. Set it up, point it at the sky, and start observing within minutes.

Key Features:

• 254mm (10") aperture for excellent light gathering
• 1250mm focal length (f/4.9) – wide field and deep-sky performance
• Smooth 2" Crayford focuser with ball bearings
• Stable Dobsonian base with easy manual tracking
• Quick setup – no alignment required
• Enhanced mirror coating for brighter images
• Cooling fan for faster temperature stabilisation

Built for Deep-Sky Observing

The 10" aperture significantly increases light gathering compared to smaller telescopes, revealing faint galaxies, nebulae, and star clusters with greater clarity and detail. Ideal for observers looking to go beyond the basics and explore the night sky in more depth.

Smooth and Controlled Movement

The Dobsonian mount uses low-friction bearings and tensioning springs, allowing smooth movement in all directions. Objects can be easily located and tracked manually, making it a simple and enjoyable observing experience.

Crayford Focuser

The 2" Crayford focuser provides precise, smooth focusing and supports both 1.25" and 2" eyepieces, giving you flexibility for wide-field and high-magnification viewing.

Simple, Practical Design

The telescope consists of two main components for quick assembly and transport. Despite its larger size, it remains manageable while delivering a substantial increase in performance over smaller models.

What’s Included:

• Optical tube and Dobsonian base
• 8x50 finder scope
• 25mm 1.25" eyepiece
• Eyepiece tray

Best For: Deep-sky observing, galaxies, nebulae, star clusters, and general astronomy
