Description
The SVBONY SV520 is a beginner-friendly 90mm refractor telescope designed for visual astronomy. Its 90mm aperture and 800mm focal length provide detailed views of the Moon, planets, bright deep-sky objects and star clusters.
The telescope uses fully multi-coated optics to improve light transmission and reduce unwanted reflections. A 5x24 optical finder scope helps locate targets, while the manual alt-azimuth mount provides smooth horizontal and vertical movement with fine-adjustment controls for precise positioning.
The SV520 includes a stainless-steel tripod and uses standard 1.25-inch astronomical accessories. Smartphone holders are included for basic phone-assisted observing and photography.
