About Sky-Watcher Classic 250P

Where astronomy meets innovation and quality, the Sky-Watcher Classic 250P 10" Traditional Dobsonian Telescope stands out as a top-tier choice for both beginners and seasoned stargazers. This high-quality Dobsonian telescope, often referred to as a 'light bucket', offers users an unparalleled viewing experience with its large 10-inch aperture, providing brighter and clearer images of celestial bodies.

The Classic 250P is a testament to the legacy of John Dobson, the inventor of the Dobsonian-style telescope. Dobson, a Vedanta monk and a pioneer in sidewalk astronomy, was renowned for creating large aperture reflecting telescopes capable of deep sky viewing using cost-effective materials. This telescope embodies Dobson's innovative spirit, combining simplicity with functionality for an exceptional visual observing experience.

Constructed with a parabolic primary mirror made of borosilicate, the Classic 250P is polished and coated with Sky-Watcher's proprietary Radiant Aluminum Quartz (RAQ), resulting in an impressive 94% reflectivity. This design amplifies the telescope's light-gathering capacity, making it 1235 times brighter than the human eye. It's an ideal tool for observing faint objects like nebulae, star clusters, and galaxies.

The Classic 250P Dobsonian isn't just about the optics. Its sturdy base features Teflon bearings for smooth azimuth slewing and a patented tension control handle for locking the telescope in place. This ensures stability even when using heavier 2-inch eyepieces or 1.25-inch accessories, making it a versatile tool compatible with virtually any eyepiece on the market.

Included with the Classic Dobsonian are two 1.25-inch eyepieces, a 1.25-inch adapter, a 2-inch eyepiece adapter, dust caps, and a 9x50 finder scope. Staying true to John Dobson's original design, Sky-Watcher combines two mirrors, a metal tube, and a simple rocker box to create a user-friendly, stylish, and durable telescope.

Experience the joy of navigating the night sky manually with a star chart, improving your astronomical knowledge while immersing yourself in the wonders of the universe. With the Sky-Watcher Classic 250P 10" Traditional Dobsonian Telescope, you can unplug from the digital world and embark on an unforgettable journey through the cosmos.
