Skywatcher Dobson telescope N 200/1200 Skyliner Classic Pyrex DOB

Sky-Watcher Skyliner 200 Classic Dobsonian Telescope

Dobsonian telescopes are recognized as some of the most practical and efficient instruments in all of amateur astronomy. Built upon a beautifully simple foundation, they consist of two primary sections: a high-performance Newtonian reflector optical tube, and a sturdy wooden floor mount (familiarly known as a rocker box). This smart structural layout allows you to jump into stargazing sessions instantly without spending crucial time configuring or aligning complex mounts. The core objective of the Dobsonian configuration is to deliver the absolute largest aperture size for the lowest possible cost. At SkyHunters, we are proud to offer this magnificent light bucket along with our industry-leading technical support and guidance.

Key advantages

• Unrivaled Value per Millimeter: The massive 200mm parabolic mirror pulls in 820 times more light than the human eye, unlocking deep-sky objects completely hidden from smaller optics.
• Ultra-Fast Setup and Deployment: Comprising just two main modules—the optical tube assembly and the standalone rocker box—setup requires less than a single minute.
• Precision Figured BK7 Optics: Crafted from premium BK7 glass, the primary mirror features a surface accuracy of 75nm PTV or better (exceeding Lambda/8 specifications) and maintains a Strehl ratio of 0.8+, certifying it as diffraction-limited.
• Patented Tension Control System: Provides integrated friction adjustments along the altitude axis, enabling you to tailor the moving resistance and ensure the telescope stays perfectly balanced.
• Fluid 2" Crayford Focuser: Includes a smooth, backlash-free 2-inch Crayford focuser paired with a 1.25-inch reducer adapter for full eyepiece compatibility.

Product description

The Sky-Watcher Skyliner 200 Classic Dobsonian is a highly celebrated choice for dedicated visual observers. Popularized by John Dobson in the late 1970s, this alt-azimuth mount utilizes highly responsive slide and pivot bearings, allowing you to fluidly point the optics with nothing more than the gentle nudge of a couple of fingers. The telescope holds its position rock-solid at any angle, translating to stable, high-magnification tracking up to its maximum practical threshold of 400x.

The primary parabolic mirror boasts a 94% reflectivity rating and is fortified with an aluminum coating capped by a protective quartz layer. This high-grade layering effectively prevents spherical aberrations, focusing 80% or more of incoming starlight cleanly inside the theoretical Airy disk. Since it is strictly diffraction-limited, its sharpness is capped only by the physical behavior of light waves rather than any imperfections in the glass.

This optical system is optimized for resolving globular clusters, exploring detailed filaments inside bright nebulae, tracking external galaxies, and resolving structural contours across the Moon and planets. Outfitted with convenient carrying handles, transporting the 11kg full optical tube to dark-sky sites is effortless, creating an outstanding all-in-one exploration package for both beginners and seasoned star-gazers.
