[Utah-astronomy] Care to speculate?

While taking images of random galaxies tonight I got this of NGC 2681: JPG http://users.wirelessbeehive.com/~paw/temp/NGC_2681.JPG FIT http://users.wirelessbeehive.com/~paw/temp/NGC_2681_FIT.ZIP Anyone care to speculate what the streaks are? The image is about 18 x 26 arc minutes. 60" exposure. Other details: C-14 @ f/5.5, ST-10 binned 3x3, cooled to -10, clear filter. Just curious, patrick
