Seben Big Boss 150/1400 6" EQ3 Reflector Telescope Astronomy Scope Astronomical (59850)

The Seben Big Boss 150/1400 reflector telescope is the flagship of Seben’s astronomy series, known for its excellent build quality and impressive performance. With a large 150mm aperture and a long 1400mm focal length, this catadioptric telescope provides outstanding light-gathering ability and high resolution, making it possible to observe stars as faint as magnitude 13.8-over 5,650,000 stars visible.

The catadioptric design makes the telescope compact and easy to transport, while also reducing wind resistance during outdoor use. This compactness is especially helpful when setting up or moving the telescope, and it ensures greater stability on windy nights.

The Big Boss telescope is equipped with a modern 31.7mm (1.25") focuser, allowing compatibility with a wide range of accessories, including those for astrophotography. The package includes many essential accessories at no extra cost, so you do not need to worry about hidden charges.

Included is a 31.7mm (1.25") moon filter, which reduces glare and reveals more lunar surface detail. The 1.5x erecting eyepiece provides an upright and correctly oriented image, making the telescope suitable for terrestrial observations as well. The 6x30 finderscope helps you easily locate celestial objects.

Two high-quality Plössl eyepieces (25mm and 6.5mm) are included, offering magnifications of 56x and 215x. Plössl eyepieces are known for their superior image quality compared to standard eyepieces, laying the foundation for a quality eyepiece collection.

The sturdy, height-adjustable aluminum tripod ensures stable observations, whether you are viewing celestial or terrestrial targets. The EQ3 equatorial mount allows for precise tracking of celestial objects as they move across the sky. Unlike basic altazimuth mounts, the equatorial mount features an axis aligned with Earth’s rotation, making it easier to follow objects with minimal adjustments.
