Telescope Sky-Watcher BK 809AZ3
The Sky-Watcher BK 809AZ3 achromatic refractor will be a wonderful gift for a novice astronomer. High-quality coated optics allows you to get a clear and contrasting image across the entire field of view. This model has a reliable design. The alt-azimuth mount is easy to operate. Optics The lens with a diameter of 80 mm allows you to view many interesting astronomical objects. This model is optimal for studying the Moon and planets of the Solar System, but it can also be successfully used for observing deep space objects. To fine-tune sharpness, a rack-and-pinion focuser with a standard mounting diameter of 1.25" is used. The telescope is equipped with two eyepieces: 25 mm and 10 mm. It is better to start observations with a long-focus eyepiece. Mount The optical tube is mounted on an AZ3 azimuth mount. Thanks to the built-in mechanisms of fine movements, the mount ensures smooth and even movement of the pipe. Comfortable flexible handles are used for control.
