The National Geographic brand is known today in the most remote corners of our planet. The National Geographic Society has earned its fame thanks to its in-depth research of the surrounding world and the popularization of its discoveries and observations. Today, National Geographic cooperates with the best manufacturers of goods all over the world. The result of this cooperation is the development and production of devices that allow you to study the environment, as well as a number of products based on environmentally friendly technologies.
National Geographic MAK-90/1250 StarTracker GOTO - a telescope with excellent optics and opportunities for amateur astronomical observations. The world around you will open up from new, previously unknown sides. The telescope will allow you to observe many objects lost in the vastness of the Universe. The boundaries of the observable world will move away to infinity.
The Maksutov-Cassegrain system's coated optics will provide comfortable observation of a wide range of astronomical objects: from Saturn's rings and Jupiter's moons to outer space objects such as the Whirlpool Galaxy. On your first night, you'll be able to see more than Galileo Galilei was able to observe in his entire life!
This telescope will be useful not only for a schoolchild, but can become the center of attention for the whole family. Where, if not at the telescope, to talk about the Universe, to dream about space travel. Together with your child you will be able to study the details of the planets of the Solar System, find galaxies and nebulae, observe bright double stars and entire star clusters.
Finding objects is extremely easy thanks to the StarTracker homing system , which stores 272,000 objects in its database. The function of showing currently visible objects allows the telescope to adjust itself and show the brightest and most interesting objects in the night sky. The high speed of pointing to an object will not make you wait long, even if the next search object is on a completely different side of the sky. Many user functions make it possible to make a journey through interesting objects in space enjoyable and educational. The initial adjustment of the telescope is also not difficult. Even a 10-12-year-old child can handle it. You will need minimal participation in adjusting the position of the tube, namely, centering the tuning stars in the field of view of the eyepiece.
Powered by 6 AA batteries, your telescope is independent of the power grid, so you can easily take it with you out of town or on an outdoor holiday. The kit also includes a cable with a plug and terminals, allowing you to connect the telescope to a 12-volt power source.
A fairly wide set of accessories includes, in addition to eyepieces, such nice little things as a compass, a lunar filter, a planisphere (a movable map of the starry sky), which on the one hand saves money, and on the other allows you to immediately begin observations.
