Your 60d camera picked up the O111 well, the noise is a problem might have been a warm night. The squiggly lines are hot pixels that appear to move in reality they are in the same place but each sub has moved between exposures. Dark frames with OA guiding will solve the problem, flexing and movement of mirrors or guide scope gives this problem.The movement will show as a blacked out edge or border when you stack the image.
