14 cm diameter
planisphere made of cardboard and has a cord to carry it hanging when we go out to observe at night.
The mode of use is very easy, simply hold the planisphere with your hands, raising it inverted above the level of the head so that we can see the north of the planisphere oriented towards the real north using a compass or we will be guided by such reference points like the Polar star. From here with the arrow facing north we will go around the circumference of the planisphere depending on the day, month and year to know the constellations that can be observed tonight through the telescope.
For a good observation it is essential that there is a clear and clear night.
