Getting there.
Without being picky, there's a ring round each star which if I have understood correctly means you've over sharpened the image.
There's also a little blobbiness about the stars which could be focus or seeing when the images were taken.
I hope you don't mind me pointing out something I'm not that cluey on.
I think ypur image is great.
Not too bad Diego, well done Always great to get an image after things didn't go your way I agree with Jennifer, rings around stars are usually a sign of over sharpening/deconvolution.
