    Nothing fancy- my telephoto lens (800/5.6) and a tripod. TIF images acquired @ 1/1600s, ISO 800. No mirror lock-up, etc.

    Some notes on perspective, :smile:
    https://www.nasa.gov/feature/goddard/2017/osiris-rex-snaps-pictures-of-earth-and-the-moon
    "This black-and-white image of the Earth-Moon system was captured on Sept. 25, 2017 by NavCam 1, one of three cameras that comprise TAGCAMS (the Touch-and-Go Camera System) on NASA’s OSIRIS-REx spacecraft. At the time this image was taken, the spacecraft was retreating from Earth after performing an Earth Gravity Assist maneuver on Sept. 22. Earth and the Moon are shown 249,000 miles (401,200 kilometers) apart, and the spacecraft is 804,000 miles (1,297,000 kilometers) from Earth and 735,000 miles (1,185,000 kilometers) from the Moon."

    Captured in one of NASA's observatory in 2016. It is 20,000 light years away.
    This is called the Art of Science.
    Not literally. But this is very beautiful. Majestic.

    Deep Star Maps
    Visualizations by Ernie Wright Released on January 17, 2012
    (from NASA/Goddard Space Flight Center Scientific Visualization Studio)

    "This set of star maps was created by plotting the position, brightness, and color of just over 100 million stars from the Bright Star, Tycho-2, and UCAC3 star catalogs. The constellation boundaries are those established by the International Astronomical Union in 1930. The constellation figures also come from the IAU, although they're not official."

    My mistake. It should have said APOD (Astronomy Picture of the Day). Just click the link in the original post.

    I'm goofing off too much. My first thought at seeing that was Settlers of Catan. :oldeyes:

    The Pleiades are coming into view (for me) now. it also warmed up a bit, so being outside wasn't totally unpleasant:

    After a long winter's nap, the weather is becoming more conducive for astrophotography here in cleve-o. Last night I got this image of the Flame and Horsehead nebulae in Orion:

    2h%2017m-1.TIF%20RGB-1_zpssr1vnkt8.jpg

    2h%2017m-1.TIF%20RGB_zps2cm10qss.jpg

    Total acquisition time: 2 hours with my 400/2.8 wide-open. Single frame info: 10 s, ISO 800. Not bad for urban viewing conditions!

    Rosette nebula:

    2h%20RGB-1_zpsxsrla8wu.jpg

    2h total acquisition time @ 400/2.8, ISO 800... this is definitely one of the trickier ones.
