3 Mornings With the ISS

   A favorite pastime of mine is to watch the International Space Station orbit over my part of the world and when possible capture the flyover on film.
   This picture is from Wednesday September 21st and is a time lapse consisting of about 80 separate pictures stacked together and processed as one picture.
    The dashed line is the reflected light from the ISS and each dash represents 2.5 seconds of travel. The camera was more or less centered on Polaris, above the chimney, so as the Earth rotated stars around Polaris moved and the curved lines show the apparent circumpolar path they follow.
   Thursday morning as I was walking my dog prior to leaving for work I spotted the ISS and whipped out my cellphone and captured some of its flight as a short video. The shaky motion comes from holding onto a 65 lb. dog on a leash with one hand and the cellphone in my other hand.

   This morning I set up for a time lapse series as I did on Wednesday. With large trees as my southern horizon this flyover past the constellation of Orion and the bright star Sirius was sort of a challenge. This is a series of 10 pictures stacked to show as one picture.
