NGC 300 - only 3 hours of data. re-process

The clouds came over last night so I only got 3 hours of data on this very dim target.
10 minute binned 1x1 subs gave me almost no signal on the spiral arms
so I ended up doing 15 minute subs binned 2x2 for everything.
I wish I could have kept imaging all night to help get the noise out of the picture & to bring up the missing arms.
Maybe I can add to it on another night?
This is the first time I've tried this target & it's really too hard for the light polluted suburbs.

Taken with my new 10" f4 Newt. & QHY9 mono.
All binned 2x2 & all 15 minute frames.
6 Luminance frames
& 2 frames each of RGB.
Darks, flats & bias applied.
