Sky Watcher BK 609 EQ1 60/900 telescope
Refracting telescope designed for beginner astronomy enthusiasts who want to start observing the night sky using reliable and easy-to-use equipment. The design with a long focal length of 900 mm and a lens diameter of 60 mm allows for detailed observations of the Moon, the planets of the Solar System, and the brightest objects of deep space. Thanks to its light weight and compact dimensions, the telescope is suitable for both garden observations and trips outside the city.
The achromatic optical system ensures a bright and high-contrast image
The heart of the telescope is a lens optical system of the achromatic refractor type with a 60 mm aperture. The long focal length and f/15 lens speed effectively reduce chromatic aberration, ensuring good sharpness, contrast, and natural detail representation of observed objects.
Equatorial mount, 1.25" standard eyepiece holder
The telescope has a simple equatorial mount with micro-movements, allowing for smooth and intuitive tracking of the selected object. The rack-and-pinion eyepiece holder in the 1.25" standard is compatible with the Sky-Watcher focuser drive. The 5x24 mm optical finder allows for quick object location in the sky, significantly facilitating the start of observations, especially for beginner users.
