Yes, that image clearly shows asteroids, but the OP's image clearly shows hot pixels predominantly (there is one asteroid in there as well, but it's up and to the right of the comet near the top just right of center and is not visible the entire time - it fades out towards the middle of the animation, probably a thin layer of clouds came over as the stars fade too). One shows a point spread function (the asteroids) the others in the OP's do not. The one you posted was also taken a month prior to the OP's. Different part of the sky, different objects in the same field of view. It shows hot pixels as well which also moved with the motion of the telescope over time, but in your example the motion is vertical in the image and roughly perpendicular to the motion of solar system objects within the image including the comet and asteroids.

Incidentally, the photographer of OP's image, Pete Lawrence confirmed it was noise in the image (ie, hot pixels), and that the tracking drift of his telescope was coincidentally in the same direction as the comet over time.
"Pete Lawrence ‏@Avertedvision

@Vim_Fuego there was tracking drift between images and I suspect it was coincidentally similar to motion of comet. I can prove this later "

Here's a crop centered on the asteroid I found in the OP's image:

Based on some astrometry I ran on his image I have identified it as asteroid 2002 TY164, which was the closest asteroid to the comet in the sky that evening (not physically close though - the asteroid was about 3 times closer to earth than the comet but was itself still farther from us than the sun).
