ISS, Cassiopeia, and M-31

    Finally had an evening where the skies were clear and the temperature was above freezing! Good enough to take the camera outside and try to catch the International Space Station as it passes over my part of the world.
   This picture is actually 13 stacked pictures merged into one picture. Each of the 13 original pictures were all taken with the same aperture setting of f3.5, and ISO of 800. The shorter streaks are 3-second exposure times, while the longer streaks are 5-second exposure times.
   This flyover started in the southwest and then angled toward a maximum altitude between 60-70o as it headed toward the northeast. Along the way the ISS passed the zig-zag shape star pattern of Cassiopeia the Queen, and then passed a few degrees from the Andromeda Galaxy, M-31.
