Thanks everybody for the appreciation! For some reasons the quoting tag in the forum is not working on my PC so I cannot thanks one by one, anyway your comments are really appreciated!
I have just replaced the image in my home page with a version where I have corrected an excess of Cyan on the blue stars of the field (in particular the brightest one), so now it should be a little bit better and more balanced, in particular the invasive halo..
Thanks to everyone of you for the time you spent to comment my effort
