• High-Quality Optics: Aluminised parabolic primary mirror with a minimum reflectivity of 93% and silicon-dioxide protective overcoat.
• Precision Focuser: CNC-machined 2" Crayford focuser with 1:10 dual-speed focus adjustment.
• Included Eyepieces: Three fully multicoated eyepieces – 1.25" 9mm Plössl, 1.25" 15mm Plössl, and 2" 30mm SuperView.
• Smooth Mount Adjustments: Dobsonian base with robust roller-bearing assembly for azimuth adjustments and steel shaft for altitude adjustments.
• Right-Angled Finder Scope: Comfort and convenience with an 8x50 Right-Angle Correct Image finderscope.

Detailed Description

The StellaLyra 12" f/5 Dobsonian is crafted for dedicated astronomers who seek clarity and detail in their observations. This telescope offers 44% more light-gathering ability than 10" models, making it an excellent choice for viewing the lunar surface, planetary details, and deep-sky objects like galaxies and nebulae.

The telescope features a high-quality GSO aluminised parabolic primary mirror with a minimum reflectivity of 93%, ensuring bright and clear images. The silicon-dioxide protective overcoat keeps the mirror in pristine condition for years. The collimation knobs on the primary mirror cell allow easy adjustments, and the integrated fan ensures rapid cooling.

The CNC-machined 2" Crayford focuser with 1:10 dual-speed adjustment provides smooth and precise focusing without image shift. The focuser includes a 2" to 1.25" adapter and a 35mm focus extender, accommodating both 2" and 1.25" eyepieces.

The Dobsonian base, delivered flat-packed, is easy to assemble and includes carry handles for portability. The robust roller-bearing assembly between two metal plates allows smooth azimuth adjustments. The altitude adjustments are facilitated by a steel shaft and CNC-machined metal plates with large knurled tension adjustment knobs.

The included 8x50 Right-Angle Correct Image finderscope ensures comfortable and convenient aiming without straining your neck. The telescope also comes with three eyepieces, providing clear and sharp views right from the start.
