Star Pocket Star Kaleidoscope that faithfully reproduces the main stars and constellations in both hemispheres. It is a professional, precision-designed, "retro" style instrument. Provides a map of the night sky, labeling the major stars and constellations. Easy to use - Each section rotates separately from the others. Align the month and date section (left section) with the time (middle section) by rotating the sections until the current date and time line up with the white meeting marks. Hold the telescope vertically with the poles aligned correctly (east facing east, west facing west). Compare to the visible night sky to identify and name the stars. A flashlight is included for use when there is not enough light to see the image clearly. Simply turn on the flashlight so that the star map is visible. Covers every day/night of every year. Dimensions: 15 x 3 x 3 cm. Requires 2 LR41 batteries (diameter 7.9 mm, height 3.6 mm). Recommended age: + 6 years. Made of ABS plastic (resistant to impact, high temperatures and contact with chemicals) and plexiglass. Professional tool, not a toy. Made in Italy by Navir.
