    I once owned a 2010 Equinox, but now we are talking about motorized vehicles. Let's get back to the sky's equinox, which travels much more slowly, and lasts longer.

    At this point, you might say: “You call this an eclipse?” Good call, the moon is barely inside the earth’s shadow.

    The eyes alone are superior to the telescope for some types of viewing, such as watching meteor showers and learning the constellations.

    The eclipse path for a lunar eclipse is big, about half the earth. Whoever can see the moon can see the lunar eclipse.

    Astrology is not astronomy; astronomy does not care where the planets were when you were born. Astronomers are much more concerned about where they are tonight.

    I could not afford to buy them so I built my own in 1983 for about $400.

    My dream telescope (well binoculars). These were very popular among Japanese comet hunters in the past decades.

    How can you determine Universal Time? One way is to call Greenwich and ask them what time it is there. - Don Machholz
