Detailed Description

The StellaLyra 16" f/4.5 Dobsonian telescope stands out with its impressive 16" aperture, making it a powerhouse for deep-sky observation. Built with high-quality materials by GSO, this telescope ensures durability and outstanding performance.

Equipped with a parabolic primary mirror coated with aluminium and SiO₂, it guarantees bright and clear images. The collimation knobs on the primary mirror cell allow for quick and tool-free adjustments, while the integrated cooling fan speeds up the cooling process, ensuring optimal performance. 

One of the standout features of this telescope is its dual-speed Crayford focuser. This precision component allows for smooth and accurate focusing, with a 10:1 fine focus adjustment that ensures no image shift. The focuser includes a 2" to 1.25" adapter, enabling the use of various eyepieces and accessories. The included 35mm focus extension tube makes it easy to achieve focus with longer focal length eyepieces.

The telescope's design includes six carbon fibre trusses that ensure rigidity and portability reducing weight, making it suitable for transport in most cars and setup. The open design allows for quicker temperature equilibrium for better performance. The CNC machined locking points and truss arrangement ensure robust and rigid construction that effectively holds collimation.

The telescope's Dobsonian mount is designed for stability and ease of use. It features a robust roller-bearing assembly for smooth azimuth adjustments and a steel shaft with CNC-machined plates for precise altitude movements. Large knurled tension adjustment knobs allow for easy altitude adjustment, while the balance adjustment mechanism ensures precise balance when switching between different eyepieces or adding accessories.

For added convenience, the telescope comes with an 8x50 Right-Angled Correct Image finderscope, making it comfortable to locate celestial objects without straining your neck. The finderscope's large 50mm aperture helps spot dimmer targets with ease.
