Sky-Watcher BK 909 EQ3-2 Telescpoe

The telescope in a classic achromatic refractor configuration is adapted for detailed observations of the Solar System as well as brighter deep-sky objects. Its optical system with a 90 mm diameter lens and a 900 mm focal length ensures excellent image sharpness.

The optical system with a lens speed of f/10 enables sharp and contrasting images, which is particularly important when observing the Moon and planets, where precision in detail reproduction is required. The telescope also allows for the detection of surface structures and subtle differences in the brightness of observed objects.

A magnification range from 13x to 180x allows for adjusting the image to the observed object. The device features a light-gathering ability 165 times greater than the human eye, which enables the identification of fainter objects. An adjustable tripod with a height of 71-123 cm allows for adaptation of the workstation to the user's needs, and a tube length of 910 mm ensures stability of the optical system.

The telescope is equipped with a standard 1.25" rack focuser, which allows for precise focus setting. The design is compatible with Sky-Watcher drives, allowing for further expansion of the set. The mounting with a screw stabilizes optical accessories during observation.

The model includes an EQ3-2 equatorial mount, allowing the telescope to be guided along the motion of the celestial sphere. The solid construction of the head ensures stability even at higher magnifications, and the micro-movement knobs allow for precise setting in both axes. The mount is adapted for connecting drives, facilitating object tracking during longer observation sessions.
