Here is a 5 hour shot of M63 Sunflower Galaxy calibrated, stacked and processed in APP. 

Small amount of PS for background and taming large star diffraction from focuser screws in the light path.

LPC saving my bacon again with 3 led street lights beside my garden.

That's lovely, also nice to get the colors nice in the galaxy with those pesky lights around!

Thanks. This is the 🥈 n last images with the Intes and my last one (Leo triplet) was possible with a driver fix to camera. Bayer drizzling reduced noise a lot, leaving me with an image that was all APP, except for HLVG in PS.

Side query: increasing all green to magenta is HSL tool for 0-100% dyn range while reducing saturation does not work as well as sncr or HLVG. Is there a better way to remove remaining green noise?

You can also do a stronger effect during star color correction, which also has sliders to tune that. The HSL is more subtle yes and also can require a few of the color channels to be changed a bit regarding that to reduce the cast, maybe also try to go through those selections in the tool and move to magenta a bit.
