Star glow/aura/spikes

Just looking for some feedback as to why the bright stars in my images are showing extreme shine/spikes etc.
I have recently changed from DSLR AP to purchasing an ASI183MC Pro, I am seeing a lot of my bright stars wit this extra shine or glow/rays. I thought it was focus, but I have spent a long tine in ASI air working to the lowest fwhm in focus mode could it be back focus? I have set it at the recommended distance. Is there something wrong with my optics
I have attached a single 100gain 180sec exposure for reference. Would appreciate help on this
