    But I had my fun.

    As you all know, the Earth made it's closest approach to the Sun for the year on Jan3.
    This is called perihelion.
    The Moon makes it's closest approach to Earth every month at perigee.
    The Moon's farthest distance from Earth each month is called apogee.
    (As you may have surmised, "peri" is Latin for "near" and "apo" is Latin for "far")
    The Moon's diameter changes significantly between apogee and perigee, although you cannot detect that with the naked eye. The media makes a lot of hype about a "Super Moon", which occurs when the Moon is full at perigee. But a Super Moon looks the same as any other Full Moon.
    I thought it would be cool to capture images of the recent apogee and perigee Moons and compare them to the Sun's image at exactly the same magnification, which allows you to see the actual size difference. I got too time on my hands. Ticking away from me.
    I also included a Hydrogen-Alpha image of the Sun on perihelion day.
    All images are at 40X. Picture1.jpg Picture2.jpg Picture3.jpg Picture1.jpg Picture2.jpg Picture3.jpg
