Comet Jacques Video

Comet Jacques came flying through Cassiopeia in late August 2014.  After a wonderful night of imaging the Veil Nebula, I had some time in the early morning after the Veil had set behind the house.  I caught Comet Jacques as it passed the meridian.

The Comet was hard to find.  My usual planetarium program and the first two websites I checked gave incorrect locations.  I found the Comet's true ephemeris when I went to The Sky Live (http://theskylive.com/).

Anyway, this video (really a slide show) shows the comet's movement in 100 30-second frames.  The comet was moving so fast that frames much longer than 30 seconds showed the comet as a line.  The movement would have been easily visible in a telescope over a few minutes' time.  Here is the link:


I have not stretched these images much.  You might see more if you make the video full screen.
