Telescope Skywatcher BK 1141EQ1

The Sky Watcher BK1141EQ1 telescope offers an affordable price, high mobility and extensive equipment. It is the ideal model to introduce to the world of amateur astronomy and is often chosen as the first telescope. A special system has been built into the optical axis of the telescope, extending the focal length of the telescope to 1000 mm while maintaining the compact dimensions of the tube.

Optical system:

Reflecting telescope (Newton system) with an aperture of 114mm and a focal length of 1000mm. Due to the moderate focal ratio, the telescope allows you to observe both planets and the moon as well as bright deep sky objects such as star clusters or nebulae. The telescope with this aperture can see about 190 times more light than the human eye at night, providing the ability to observe objects up to nearly 12 magnitudes (with the naked eye visible up to 6 magnitudes). The size of the mirror is also related to the optical resolution, which in this telescope enables it to separate stars that are more than 1.2 ”apart.

Assembly:

The EQ1 parallactic assembly is equipped with micromovements and allows for setting the telescope according to atlas or sky maps and smooth movement along the right ascension and declination axis. The assembly should be properly set and aligned with the North Pole of the sky, thanks to which we will be able to operate the telescope in a simple and convenient way. The assembly can be fitted with a drive which will enable automatic tracking of object in the sky.

Focuser:

The telescope is fitted with a focuser that allows for the use of 1.25 ”eyepieces. The set includes two 10 and 25mm lenses with 40 and 100x magnification, and a Barlow 2x lens with 80x and 200x magnification.

Astronomical observations:

1. Solar system

-objects on the lunar surface larger than 1- 2 km in size;

- sunspots and their structure;

- all planets of the solar system;

- the phases of Venus

- Mars

- Jupiter's equatorial belts and Galilean moons

-the rings of Saturn and the largest moon Titan

-Uranus and Neptune are also within range of this telescope

- asteroids motion against the background of stars

- observations of bright comets

2. Stars

-about 1.8 million stars across the sky, shining down to about magnitude 12-12.5

-double and multiple stars separated from each other angular by more than 1.5 ".

- the colors of many bright stars

3. Deep sky objects

-hundreds of open star clusters

-Many globular clusters with clearly visible stars on the outskirts

- dozens of galaxies, the brighter ones have a visible shape

-lots of bright nebulae where structure is already visible

- beautiful planetary nebulae

Ground observations

A telescope with this type of optics is not suitable for ground observation. To invert the image, use the so-called straightening lens, thanks to which we will reverse the image back (straight).
