The Bresser brand offers a wide range of traditionally high-quality telescopes of any complexity and for all ages.
Bresser Mars Explorer EL 70/900 NG is certainly one of the most inexpensive telescopes in its class. This was achieved thanks to a new, cheaper type of NG mount, which combines the simplicity of the azimuth and the advantages of the equatorial design. This mount is perfectly balanced and practically does not allow unnecessary vibrations of the telescope. At the same time, the optics are of very high quality and, in combination with a large aperture of the objective, can satisfy many demanding users.
This achromatic refractor will allow you to distinguish more distinct contours of the lunar mountains and 5 km craters, the seas and seasons on Mars, the Cassini gap in the rings of Saturn, the Crescent of Venus, Uranus and Neptune in the form of small disks. On Jupiter, you can see the Great Red Spot and even the shadows of the planet's satellites. The view will also include faint stars (up to 12 stellar magnitudes), many nebulae, and all objects in the Messier catalog. Using an aperture filter, it is possible to determine the structure of sunspots.
The optical viewfinder will make it much easier to pre-target the device to the object of interest, and the NG mount of the telescope will allow you to fix the device even on moving objects and not lose them from your field of view. Software, a lunar map and other useful literature in the telescope kit will help you figure it out, gain superficial knowledge and delve into the features of astronomical science.
Due to the ease of assembly/disassembly, reliability of the lens optical system, and the light weight of the mount, the telescope can be easily transported without fear that something will happen to it. And the quality of the images obtained, provided by high-quality achromatic optics, will not disappoint not only a beginner, but also a more experienced astronomer.
