What have I done wrong?

i was taking two-minute guided images with a canon 70d on an 8' celestron scope

can anyone suggest what i've done wrong here … the stars have a funny shape … sort of like a comet ... not just on the periphery, but even towards the middle of the image.
could the likely cause be:

tripod not level;

bad polar alignment;

something to do with focus,

scope not properly balanced.

thanks for reading.
