A large Newtonian telescope system mounted on a 25cm Dobsonian mount. Characterized by its high light-gathering efficiency, this classic Newtonian reflector excels at deep-sky observation of nebulae when used under dark skies. The substantial aperture also allows for high-detail views of the planets within the Solar System and the Moon.
Even with its impressive performance, the telescope remains relatively affordable, making it a solid choice for both beginners and experienced astronomy enthusiasts seeking capable equipment.
Pyrex mirror
All Sky-Watcher Dobson 8" and larger telescopes feature a primary mirror crafted from PYREX-glass, known for its low thermal expansion. This material ensures greater image stability and clarity compared to standard glass mirrors.
Optical system
Built around the classic Newtonian design, the telescope boasts a parabolic primary mirror measuring 250 mm in diameter with a 1200 mm focal length. The large focal ratio of f/5 provides a balance of light-gathering and compact size. The moderate focal length supports lower magnifications, ideal for observing faint, diffuse deep-sky objects with comfort.
Mount
The Dobsonian mount features a robust, simple design, allowing for smooth maneuverability on both altitude and azimuth axes. Fork mounts on either side support the optical tube, while the upper section rotates atop the base. Thanks to its low center of gravity and the use of sturdy materials, the mount offers greater stability compared to many equatorial systems.
Focuser
Equipped with a 2" eyepiece focuser and a 1.25" adapter, the telescope utilizes a Crayford mechanism for precise, backlash-free focusing. Both a 2" extension tube and a 1.25" adapter are included, intended for alternate use rather than combined operation.
