You could take some flat frames and apply them. Did you do darks?
Guiding needs some work, unless thats an optical aberation. looks like its in different directions so more likely the later - or its field rotation in which case you need to be better polar aligned. What were your sub lengths?

more time will help get rid of the graininess.

Is that light polution? if so, you may want to look at a LP filter.
