The Sky-Watcher Classic 250P Dobsonian features a massive 10-inch aperture and sturdy Dobsonian design, offering exceptional light-gathering power and impressive image resolution. This simple yet effective design is perfect for visual observation of faint objects, such as nebulae, star clusters, and galaxies. With parabolic mirror Newtonian optics and very thin (only 0.5mm) secondary mirror spider vanes to reduce diffraction, the Moon and planets are sharp and well-defined. Weighing only 56 pounds fully assembled, the Classic 250P delivers premium optical performance in an affordable, transportable package ideal for both beginning and experienced amateur astronomers.
