Statue of Liberty NGC 3576

I had a go at this a few nights ago under almost full moon.
I am in a Bortle 3 area and wanted to try out the Optolong L-Ultimate filter and see how it goes under almost full moon.
Ideally, i want to try this filter out on this same nebula with no moon to see how it compares to not using any filters at all.

I managed to get 40 x 300 second subs in the one night.
Was hoping to get a few more nights on this one, but cloud forcast isn't looking too promising.
Calibtated with Flats, Darks, Bias
Stacked and processed with PixInsight.
Skywatcher Esprit 150 at 1050mm FL
iOptron CEM120 mount with PHD2 guiding.
asi2600mc

The images here are rotated 90 degrees as i messed up and forgot to check framing.
3 slightly different approaches to processing, still a beginner with PI
They look grainy here on this pc and at this size ( not sure if it just my poor monitor or how this site shows them, but on my image processing pc and home tv they are fine

I think the first one may be my pic of the three.
