01-14-2013 Right: Composite of 20 Frames Showing the path of the comet. That is NOT a tail...... But rather the path traveled.
Left:    The same 20 frames But in motion. 1 Sec / frame Total Time Imaged = 2 Hours (6 Min Per Frame)
03-16-2013  AAMM  Salome, AZ Right: 20 Frames in Motion.  Each frame is a stack of 3 - 2 min exposures (6 min total). The sequence thus covers 120 minutes (2 Hours). The image is 7 arc min wide. It has been reported that ISON has developed a tail. And, it seems that a tail is showing here.
