Thank you guys for your comments
In the last few days I have upped my game and managed to get a decent set of exposures (about 70 exposures of 300s). Took also some calibration frames and had my first steps in Pixinsight.
Sort of a rushed processing tonight - pretty happy with the overall result and not so happy with the number of stars in the image.
I will definitely go back in the next few days and hopefully I will get a better result.
Here is is a shot of Lagoon Nebula and Trifid Nebula in the same frame.
