A lunar eclipse occurs when the Moon passes within Earth's umbra (shadow). As the eclipse begins, the Earth's shadow first darkens the Moon slightly. Then, the shadow begins to "cover" part of the Moon, turning it a dark red-brown color. The Moon appears to be reddish because of Rayleigh scattering (the same effect that causes sunsets to appear reddish) and the refraction of that light by the Earth's atmosphere into its umbra.
The following simulation shows the approximate appearance of the Moon passing through the earth's shadow. The Moon's brightness is exaggerated within the umbral shadow. The northern portion of the Moon was closest to the center of the shadow, making it darkest, and most red in appearance.
The second is an ebony and ivory sextant in original box, c1840. A sextant is a doubly reflecting navigation instrument used to measure the angle between any two visible objects. The primary use of a sextant is to determine the angle between an astronomical object and the horizon for the purposes of celestial navigation. Here at Greene & Greene, we couldn’t think of anything better for an astronomy enthusiast.
