Good effort there !!
Looks like your ISO maybe too low as most Canons sweet spot is 800
My 600D is always set to 800 regardless if I’m imaging at my home in Sydney ( Bortle 8 ) or at my holiday home near Ulladulla ( Bortle 3 )

Also try and push your subs a bit longer if can

Give Startools a trial , it works beautifully to remove all types of gradients and noise

My image of Centaurus A was in Sydney ( Bortle 8 ) and the subs were 3 or 4 minute at ISO800. On the laptop the raw frames looked like a white sheet and when the stacked image was processed through Startools it cleaned up beautifully
Give it a go , there’s no levels , curves , histograms tweeking to do to it’s really intuitive

Cheers
