They come in a variety of styles, from metallic and futuristic, to traditional and antique. Orrery kits are made of a wide range of materials.

As with their appearance, material selection is largely a matter of taste. Do you want one made of brass? With respect to craftsmanship, you get what you pay for. These products vary wildly in terms of the love and care that went into their construction. That being said, the pricier items on this list can last for many years, especially when handling is kept to a minimum.

The kind of product you select will depend on what you want to accomplish. Do you hope to educate a child about the workings of the solar system? You may wish to avoid the simpler products on this list. Are you looking for a simple orrery kit to decorate a desk with limited real estate? The more limited products may be right up your alley.

Long gone are the days that the orrery was the standard method for predicting the positions of celestial bodies. As a result, the accuracy of these products, with a few exceptions, is limited.

Buying a gift for someone close to you, but not too close, is always a difficult proposition. People we know well but not too well tend to already own the items common as gifts for such folks bestseller books, ties, and movies , but buying them something too off-the-wall is likely to backfire.

Key chain torch with red LED for undisturbed night vision. The indispensable tool for all star gazers! Everybody knows the effect that when you switch on the light at night, you are dazzled at first until your eyes have adjusted to the sudden brightness.

If you then switch off the light, it takes quite a while until your eyes have readjusted to the darkness again. The reason for this is the pigment rhodopsin that is produced in the eye when it is dark and that multiplies the sensitivity of the eye. Bright light rapidly breaks down the pigment which reduces the sensitivity of the eyes severely.

That is why you feel nearly blind at first when you step from the light into the dark. It takes at least 20 minutes in the dark until the maximum level of rhodopsin is reached and you have gained full night vision.

Red light has no effect on the rhodopsin level in your eyes, so using our Red Sight Lamp for orientation when you are out stargazing will preserve your night vision.

At first it looks just like an ordinary ring. Looking a bit closer, you will see that it consists of five separate interlocked rings that can be rotated around their axes. This way the ring can be folded out to form a miniature planetarium. The inscriptions are inspired by the astrologically motivated astronomy of the 16th century:. On the outside of the middle inner ring you will find the symbols for the signs of the zodiac.

The two inner rings are inscribed with the four classical elements fire, air, water, earth in Latin, German, and English. Extra sharp knife, ideal for cutting cardboard. Blade consists of separable sections and can be sharpened up to 12 times by breaking off the blunt part.
