Telescope Sky-Watcher BK 909EQ2
The BK 909EQ2 telescope from Sky-Watcher is designed to study solar system objects, but is also suitable for deep space observations. Multi-layer coated optics produce a clear and sharp image across the entire field of view. The optical tube is mounted on a rigid equatorial mount EQ2, which allows you to compensate for the daily rotation of astronomical objects. The BK 909EQ2 amateur astronomer telescope is an achromatic refractor, so chromatic aberrations during observation are minimized. The lenses are coated with a multi-layer anti-reflective coating, which significantly improves image quality. The telescope is equipped with 25 mm and 10 mm eyepieces - for overview observations and detailed study of selected objects. The EQ2 equatorial mount is equipped with mechanisms for fine movements along the declination and right ascension axes. Sky-Watcher BK 909EQ2 can be used for astrophotography; To achieve the smoothest possible movement of the optical tube, the mount can be supplemented with a motor drive (purchased separately). The aluminum tripod is height adjustable.
