Telescope Skywatcher BK767AZ1

Description

A very lightweight reflector telescope, ideal for newcomers to sky observation. It is the ideal model for entering the world of amateur astronomy and is often chosen as the first telescope. Due to the focal ratio of f / 9, this telescope is particularly suitable for observing bright objects in the solar system, such as the moon and the planets. This model will also prove its worth when observing the brightest deep-sky objects such as star clusters or nebulae.

Optical system

Reflector telescope with an aperture of 76 mm and a focal length of 700 mm. The main advantage of this telescope is its compact size. A telescope with this aperture can see about 120 times more light at night than the human eye and allows the observation of objects up to 11.8 magnitudes (up to 6 magnitudes are visible to the naked eye). The size of the mirror is also related to the optical resolution, which allows this telescope to separate stars that are more than 1.8″ apart. It is recommended to extend the set with an additional eyepiece with a focal length of 7-8 mm, which is used for observing planets and the moon, and another one with a focal length of 30-40 mm to obtain a larger field of view.

Assembly

The AZ1 is a simple and lightweight azimuth mount. It is equipped with a special system for adjusting the vertical and horizontal position, which makes it easier to observe and track even very distant objects. The mount is ideal for astronomical observations, but can also be used for simple terrestrial observations.

Focusser:

The telescope is equipped with a focusser that allows the use of 1.25″ eyepieces. The set includes two 25 and 10mm eyepieces with 28x and 70x magnification and a Barlow lens with 57x and 140x magnification.

3. fog objects

Most Messier objects are within the range of this telescope, the best results are obtained when observing in areas with low illumination
most globular clusters
dozens of open star clusters
some brighter nebulae
bright galaxies that show their shapes

Ground observations

A telescope with this type of optics is not suitable for ground observations. To invert the image, we use the so-called erecting lens, thanks to which we can invert (straighten) the image. Together with the erecting lens and the mount on which it is placed, it can be used as a simple ground observation device.
