I suspect your high ISO is part of the problem. Normal recommendation is about 800-1600 max. You may have to do more exposures to collect more photons but the result should be more accurate and cleaner.
Also what was the ambient temperature while you were shooting ? The hotter it is the more noise and other issues occur.
How bad is Light Pollution from your imaging site ?

Time for guiding methinks to be able to cut the ISO and up the exposure time. Ambient temp was not too bad, somewhere between long sleeve shirts and time for a jacket. LP is also pretty good from home, we are about 50KM away form the outskirts of Melbourne and 6KM out of a smallish town so about as good as it gets without going out to a proper dark sky site.
A fair few of Andy01's images are shot from my place.
