Hi guys, I am currently shooting but 90% of my images are coming out with these weird star trails. 
I am not sure, but I believe it may be linked to my guide acting up but below is how it's working at the moment. Not sure if anyone has had this issue before? Please help!! I am using an HEQ5 mount, with a William Optics Z61II, ZWO ASI294MC Pro, and guiding with the Uniguide 32 and ASI120MM Mini.
