This small plastic accessory 20cm x 20cm can answer these questions: just rotate the hour disc to put your time in front of the date.
Appears while in the transparent window the sky map with the visible constellations and their major stars, at least the larger among those visible to the naked eye.
As a bonus, a transparent strip rotating independently measures the position of the stole in the sky, horizontally and vertically.
Of course, you will not see nor the moon or the planets obey other laws than the simple rotation of the Earth on its axis inclined.
But for the constellations and stars, this accessory usefully accompany binoculars or a telescope, or just your eyes to admire the sky.
By cons, you need eyebrows or have good glasses because the window is small and the constellations and their stars are numerous and dense.
